Just why

#inflation

It costs more than a penny to make a penny. There are powerful lobbyists for the zinc (the main metal in a penny) industry making sure that the penny stays in circulation. Why? Because pennies are the #1 market for zinc and your tax dollars pay all the bills. Same with the nickel and the nickel industry, coins are being made at a cost of more then they're worth so that a resource that has very little value can be forced onto the American people for huge profits. We are suckers, all of us.

Oh i see :o thanks for the explanation

That sounds great but it wouldn't really change anything, also banks don't produce money. The money still has to come from elsewhere and is in basic form a means of showing worth to a given object or service. Giving money with a reciprocal exchange doesn't increase anything in fact it generally causes a drastic decrease. Think about it pragmatically, if you were just given money with no expectation to return that money or do anything for it would you A, just take the money say thanks, spend and wait around for your next hit or B, take that money and work hard to generate a better more self sustaining source of income for yourself on top of the the free money your getting. The answer is almost always A. That means that those actually generating income will have to have more of their hard won money removed form them to support a system that rewards doing nothing. I'm not saying are schools shouldn't be funded or the homeless helped but there are better and more worthwhile approaches.

Also you want schools to be better funded? Start paying teachers what a doctor makes. Show kids there is a real reward for studying, learning more and passing it on to others. This would lead to better more motivated teachers which in turn teach better, and the students will reap the rewards of having better teachers meaning a better education. Better educated people, means more opportunities, more ways to generate that income that everyone wants or needs.
