Since you have asked two questions, and the second question is a little unclear, I will answer the first question.

Laissez-faire policies have had an impact on the United States throughout the years. Throughout the 1800s, laissez-faire policies dominated our political thinking. The government tried to stay out of the actions of businesses and also tried to stay out of any major involvement in the economy. Eventually, when problems developed with unsafe working conditions, the exploitation of workers, the lack of involvement of common people in politics, the lack of protection for consumers, and the deterioration of our environment, the Progressives, around 1900, demanded and got many changes to improve these conditions.

A very good example of the laissez-faire philosophy could be seen in the 1920s and at the beginning of the Great Depression. The government again stayed out of the affairs of businesses and had a very small role in the economy. Even when the Great Depression began and became worse, the government stayed out of actively trying to resolve the Great Depression. Eventually, President Hoover became more involved in trying to end the Great Depression. When his actions were unsuccessful, people turned to Franklin D. Roosevelt who promised a lot of government action to help ease the effects of the Great Depression and to try to prevent another such depression from occurring.

Today, we are also seeing a renewed emphasis on a low-key government approach. Republicans tend to support a limited involvement of the government in the economy with fewer rules and regulations for businesses to follow. The Democrats are taking the opposite of the role of government in the economy and in the affairs of businesses. Republicans have taken control of Congress and several state governments by advocating for laissez-faire policies and ideas.

Laissez-faire policies have affected us in the past and also affect us now.
