The majority of the people have to be ready to accept the solution to a problem proposed. Truman was the first to to propose Medicare on 5 Jan 1949. The people nor congress was ready for it then. JFK tried to get Medicare passed in 1962 and again in 1963, failed. It wasn't until 1965 that the public and congress was ready for it.

That is a span of 15 years. But it was accomplished.

It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
