Why the US Government Invests So Much in the USA

Why does government in the USA invest enormous amounts of money in the United States of America?

Current spending proposals would push an expansion of federal government power and spending to a level not seen since the mid-1960s... Actually you might want to consider the New Deal of the 1930s as well;

Time to review what JFK said while speaking at Rice University in 1962 (  https://er.jsc.nasa.gov/seh/ricetalk.htm  );

The Transcontinental railroad required, at a minimum, eminent domain;

The Interstate highways: federal government;

Local roads: local governments;

Airports and seaports: FAA and port authorities;

Federally Funded Research and Development Centers (FFRDCs), Defense Advanced Research Project Agency (DARPA), etc;

The government made the devices you'll use to review this document, if you do review it, possible;

The vaccine that keeps you safe from Covid: NIH, CDC, etc;

There is so much more. This is what has made the USA the USA. This is why the government invests amounts, that only government can, in these United States of America.
