Gasoline should be free...
Food should be free...
Housing should be free...
Automobiles should be free...

Who is "they"?

Or would you have those that "use above a certain amount" pay for those oh, so poor folks below them?
Perhaps we can get some advice on this problem from Karl Marx.
Man...you can’t fix stupid or inbred...don’t waste your time trying to reason with idiots. Life’s too short!
