These are the four points raised, as a "good idea", in the OP:

1) making sure all in the nation have food
2) making sure all in the nation have shelter
3) making sure all in the nation have medical care
4) making sure all in the nation have education

How should the government go about ensuring that all US citizens have those things? There are over 300,000,000 people in those country. Even community college tuitions would be astronomical...

Like I said, it's easy for a person to say that something should be done when that person has absolutely no intention of suggesting how it should be done...
