Period 9: 1980–Present

Period 9 runs from 1980 to the present. It examines continuing debates over government, economic and demographic change, and the United States' role in the world.

The conservative movement 保守主义运动 that organised in the 1960s and 1970s came to power with Ronald Reagan 里根. Its programme had three strands:

• Tax cuts 减税 and deregulation 放松管制, on the argument that reducing the burden on business would raise growth - often called supply-side economics 供给学派经济学.
• Efforts to reduce domestic government programmes met resistance; defence spending 国防开支 increased as part of the military buildup 军备扩张.
• Appeals to social conservatism 社会保守主义, on religion, family, and law and order.

Tax cuts and deregulation changed policy, while opposition and the popularity of many programmes limited attempts to shrink government. Debates over free trade 自由贸易, the social safety net 社会保障网 and financial regulation 监管 continued.

Try it — identify the goal. Teacher-written cases grounded in CED Topics 9.2 and 9.3: tax cuts and deregulation aimed to encourage private economic activity; the military buildup opposed communism; social conservatives promoted traditional values. Match these to economic, foreign-policy and social goals. Does the military case fit “less government in every field”?

Worked comparison. The coalition combined different goals. Supply-side reasoning stressed incentives 激励 for work, saving and investment; military policy used federal resources; social conservatism involved values beyond the economic argument. Reduced regulation did not mean federal power disappeared.

Source practice — Reagan's September 1981 economic-recovery address, paraphrased. Reagan expected tax cuts to stimulate growth and jobs, spending restraint to reduce deficits 赤字, and less regulation to ease business burdens. Identify a policy and its intended effect. What further evidence would establish whether the aim was achieved?

Worked reading. A speech establishes the administration's argument, not independent proof of success. Compare implementation, economic performance and budgets. The CED records tax cuts and deregulation alongside resistance to shrinking popular programmes. Do not treat expected growth as a universal rule that tax cuts pay for themselves.

Renewed military build-up, negotiation, and above all internal weakness in the Soviet Union brought the Cold War 冷战 to an end. The Soviet system collapsed between 1989 and 1991.

The consequences framed the decades that followed: the United States became the sole superpower 超级大国, with unresolved questions about when and where to intervene, and about what commitments made sense once containment 遏制 no longer organised policy.

Three developments help describe the economy after 1980:

• Globalization 全球化 - cross-border trade, production and economic connections.
• Deindustrialization 去工业化 - declining manufacturing 制造业 employment, alongside growth in service work 服务业工作.
• Technological change 技术变革 - computing and then the internet, which transformed productivity 生产率, work, and communication.

Digital communication increased productivity and worldwide economic opportunities. These gains coexisted with stagnant working- and middle-class real wages 实际工资 and growing income inequality 收入不平等.

Try it — identify developments and overlap. Teacher-written cases grounded in CED Topic 9.4: A, digital communication helps a business reach customers abroad; B, manufacturing employment falls while service employment rises; C, computing and the internet change work and access to information. Match the cases to globalization, deindustrialization and technological change. Can one case involve more than one development?

Worked classification. A involves global connections and technology. B describes a sectoral employment shift; it does not establish that every job moved abroad or that manufacturing vanished. C concerns technology's wider effects. Identify the pattern before explaining its cause.

Try it — assess distribution. The CED describes increased productivity alongside stagnant working- and middle-class real wages and rising inequality. Does higher productivity prove all workers gained equally?

Worked judgment. Productive capacity and income distribution are different. Growth can coexist with unequal gains. Employment shifts and declining union membership 工会会员人数 describe the setting, but listing trends does not measure their causal weights. An explanation needs evidence about the group, dates and mechanism.

Migration 人口迁移 and immigration 移民 in the 1990s and 2000s continued to reshape the population, with growth in arrivals from Latin America 拉丁美洲 and Asia following the 1965 reform of immigration law.

The consequences are the examinable part: population growth in the South and West, the growth of multi-ethnic cities, ongoing debate over immigration policy 移民政策 and border enforcement 边境执法, and continuing arguments about citizenship 公民身份 and national identity 国家认同 - the same argument the course has traced since Reconstruction 重建时期.

The period's later topics group around a small number of developments:

• The September 11 attacks 九一一袭击 and the response - military intervention abroad, a new security apparatus, and renewed debate over the balance between security 安全 and civil liberties 公民自由.
• Economic crisis in 2008 and the argument over government's role in stabilising the economy.
• Political polarisation 政治极化, amplified by changes in media and communication.
• Debate over climate 气候 and energy policy 能源政策.

Practise causation by explaining mechanisms with relevant evidence. Possible connections across periods include deindustrialisation to the market revolution's regional specialisation, immigration debates to the nativism 本土主义 of the 1850s and 1920s, and arguments over federal power 联邦权力 to the New Deal 新政.

Exam transfer — 2025 AP US History, Set 2, long essay Q4, paraphrased. Evaluate how United States society responded to economic changes from 1960 to 2000. Explain a response rather than only naming a change. Connect computers to changing employment, then develop another relevant example such as migration toward the Sun Belt 阳光地带 or a policy debate. This unit supplies evidence for part of the question's dates.

Teacher-written model passage. As computing became more important to the late-twentieth-century economy, Americans increasingly worked in service and information-related jobs. Computer-based work supported white-collar opportunities, while access to these opportunities was uneven, especially for workers without college education.

Why it fits. The official scheme accepts computers and the service economy as evidence when used to explain jobs and class opportunities. This is one developed passage, not a complete long essay or official sample. A full response needs an argument and further developed examples; a limiting phrase alone does not guarantee complex understanding or credit.

Each part needs only one or two sentences: answer the question, cite one specific piece of evidence, and explain how it supports the answer.

Answer (a), (b) and (c).

(a) Briefly describe ONE policy of the 1980s that reflected conservative ideas.

(b) Briefly explain ONE cause of the end of the Cold War.

(c) Briefly describe ONE effect of globalisation on the American economy.

Model answer.

• (a) The Economic Recovery Tax Act (1981) cut income tax rates, reflecting the conservative belief that lower taxes and smaller government would spur growth.
• (b) Mikhail Gorbachev's reforms and the Soviet Union's economic weakness loosened control over Eastern Europe, leading to the collapse of the USSR in 1991.
• (c) Agreements such as NAFTA (1994) and competition from abroad moved many manufacturing jobs overseas, while service and technology jobs grew.

• Distinguish the supply-side economics argument from outcomes. Explain policy changes and the limits of attempts to shrink government.
• The Cold War's end matters for what it opened: sole-superpower status and unresolved questions about intervention.
• Keep globalization, deindustrialization, and technological change as distinct, sometimes overlapping developments. Explain mechanisms rather than only listing labels.
• For immigration after 1965, name the shift in origins and the political argument it produced.
• After 2001, the examinable tension is security against civil liberties - the same tension as the Red Scare and the First World War.
• Long-span prompts reward connecting periods. Link a recent development to an earlier one and say what continued.
