When a man spends his own money to buy something for himself,
he is very careful about how much he spends and how he spends it.
When a man spends his own money to buy something for someone else,
he is still very careful about how much he spends, but somewhat
less what he spends it on. When a man spends someone else's money
to buy something for himself, he is very careful about what he
buys, but doesn't care at all how much he spends. And when a man
spends someone else's money on someone else, he doesn't care how
much he spends or what he spends it on. And that's government
for you.
