但是，自由企业是有限度的。美国人一直认为，一些服务更好地由公共而非私营企业执行。例如，在美国，政府主要负责司法，教育（尽管有许多私立学校和培训中心），道路系统，社会统计报告和国防。此外，政府经常被要求干预经济，以纠正价格体系不起作用的情况。例如，它规范了“自然垄断”，它使用反托拉斯法来控制或分解其他业务组合，这些组合变得如此强大以至于可以超越市场力量。政府还解决了市场力量无法企及的问题。它为无法养活自己的人提供福利和失业救济金，因为他们在个人生活中遇到问题或因经济动荡而失去工作;它为老年人和贫困人口支付了大部分医疗费用;它规范私营企业以限制空气和水污染;它为因自然灾害而遭受损失的人提供低成本贷款;它在太空探索中发挥了主导作用，这对任何私营企业来说都太贵了。在这种混合经济中，个人不仅可以通过他们作为消费者的选择，而且可以通过他们为制定经济政策的官员投票来帮助引导经济。近年来，消费者对产品安全，某些工业实践带来的环境威胁以及公民可能面临的潜在健康风险表示担忧;政府通过建立保护消费者利益和促进公共福利的机构作出回应。美国经济也在其他方面发生了变化。人口和劳动力已经从农场转移到城市，从田地到工厂，最重要的是从服务业转移。在今天的经济中，个人和公共服务的提供者远远超过农业和制成品的生产者。随着经济变得越来越复杂，统计数据也显示出上个世纪从自营职业转向为他人工作的长期趋势。本文改编自Conte和Carr的“美国经济概论”一书，并经美国国务院许可改编。
美国明德大学经济论文代写：自由企业
However, free enterprise is limited. Americans have always believed that some services are better implemented by public rather than private companies. For example, in the United States, the government is primarily responsible for justice, education (although there are many private schools and training centers), road systems, social statistics reports, and defense. In addition, the government is often required to intervene in the economy to correct the situation in which the price system does not work. For example, it regulates “natural monopoly,” which uses antitrust laws to control or break down other business combinations that become so powerful that they can go beyond market forces. The government has also solved the problem that market forces cannot match. It provides benefits and unemployment benefits for those who cannot support themselves because they have problems in their personal lives or have lost their jobs because of economic turmoil; it pays most of the medical expenses for the elderly and the poor; it regulates the private sector Limiting air and water pollution; it provides low-cost loans to people who suffer from natural disasters; it plays a leading role in space exploration, which is too expensive for any private company. In this mixed economy, individuals can not only help them as a consumer, but also help them guide the economy by voting for officials who make economic policies. In recent years, consumers have expressed concerns about product safety, environmental threats from certain industrial practices, and potential health risks that citizens may face; the government responds by establishing institutions that protect consumer interests and promote public welfare. The US economy has also changed in other ways. The population and labor force have been transferred from the farm to the city, from the field to the factory, and the most important is the transfer from the service industry. In today’s economy, providers of personal and public services far exceed the producers of agriculture and manufactured goods. As the economy becomes more complex, statistics also show a long-term trend of shifting from self-employment to working for others in the last century.
