When America during the war was elected by Roosevelt, he won as most of the United States supported his commitment and the New Deal. Herbert Hoover believes what he calls "rough individualism", and the government should not interfere with the problems of other people. This means that during the Great Depression people said "We are trusting in Hoover, now we are being destroyed." When Roosevelt was elected in 1932, he promised to restore American confidence and economy.
In the era of American industrialization between civil war and World War I, economic and social loss caused by dangerous and unhealthy working conditions and frequent and serious accidents caused the government to act. Early pressures on government remedies came primarily from workers' organizations. Beginning with the factory law in Massachusetts State in 1877, the National Labor Bureau investigation on labor safety and health hazards urged the labor force to successfully promote the actions of northern provincial factories. The evolution of the factory inspection system brought about a remarkable improvement. Workplace Since 1900, progressive people from the upper middle class participated in government support for workers' health and safety campaign. These reformers are trying to overcome the disadvantages of factory regulations and enforcement. Many companies added these new public approaches and set up voluntary safety plans.
During the two wars between the Civil War and the First World War, the United States was an adult. In less than 50 years, it has changed from country country republic to city state. The borders have disappeared. Great factories and ironworks, transcontinental railroads, prosperous cities, huge farmlands. It is accompanied by evil: monopolies tend to develop, factories work in poor conditions, cities can not rapidly develop and adequately accommodate or manage the population, and factory production sometimes becomes real It exceeds consumption. Responses to these violations came from American people and her political leaders - Cleveland, Brian, Theodore Roosevelt, Wilson -. They were vigorously explain the reform is ideal in philosophy, but they are realistic in their execution, it will accept the maxim that "the law is not may begin at starting from evil".
In the various wars between these major powers, conflicts of North American resources continued, but the new European colonies gradually formed a desire for independence. The revolution such as the American Revolutionary War and the Mexican Revolutionary War created a new independent nation that dominates North America. Founded in 1867, the Canadian League established a modern political landscape in North America. From the 19th century to the 21st century, the ties between North American states are getting closer and closer. Despite some conflicts, the continent of Africa enjoys peace and universal cooperation among nations, and free trade and the majority of trade between them. Modern developments include open free trade agreements, numerous immigrants in Mexico and Latin America, and drug trafficking in these areas.
