We DO have some free market roads that are handled pretty well... and we do have private roads as well...
You didn't answer my question. I want to know why you think government should be involved in building roads and highways when the free market can handle it. Or do you not think the free market can handle it?
Can you answer that or not? Its not that complicated of a question, the only reason you wouldn't be able to answer it is if you didn't have an answer.
The Interstate highway system was built using Federal taxpayers money by the Federal Aid Highway Act of 1956 popularly known as the National Interstate and Defense Highways Act of 1956 and championed by President Dwight Eisenhower.
Interstate Highways improve the mobility of military troops to and from airports, seaports, rail terminals, and other military bases. Interstate Highways also connect to other roads that are a part of the Strategic Highway Network, a system of roads identified as critical to the U.S. Department of Defense.
National Defense by the Federal Government is a requirement in the US Constitution.
Are there any other questions?
