The first role that the government plays in the lives of American citizens is helping with retirement through social security. Through Social Security and Medicare, many Americans are kept out of poverty. These programs are provided at a far less cost from the government than if they were provided by a private sector. The second role is the improvement of public health, by the advancements in public sanitation methods such as water treatments, sewer systems, and trash disposal. The last role is the building of our transportation networks. Every major mode of transportation from public transportation to airports have received critical financial support from the government.
