The Rise and Fall: Government Spending

Over the course of the current recession that we are currently in, the government continues to push out large amounts of money.  With the national debt over $12.5 trillion,(can you cite please?) the continued spending of millions and millions of dollars is not pushing it down.  But how exactly does the government keep coming up with this money, and at what cost to the citizens of the country?  Why does the government continue to spend obscene amounts of money without having it?  No matter what the government spends money on, or doesn’t spend money on for that matter, half the population of the United States is going to complain about it.
