Yes but if it's food, or heating, or shelter, then all you are is alive, which is exactly where you started. So you've 'gained' nothing (apart from another day of life) but paid out all the same. However the person charging you has made a profit.
Let's suppose you get your heating from British Gas because you don't fancy spending all day collecting wood or trying to dig up coal. You then can instead spend the day going to work and getting paid more than enough money to pay your gas bill, with enough left over to buy some other things. So actually you've gained a lot.
Anyway, slightly OT.
Back on track, I wonder if all the fuss about the health care bill just be yesterday's news after a while and just be as normal and accepted in the US as Medicare is. If so then Obama will have achieved something, no matter what else happens.
