USA could not make money out of nowhere so spending money will only require savings in other area or increase in taxes or deflation, each of which will make the situation worse.
Are you high? The US government can and does "make money" out of thin air. They print off more money which does water down the value of existing money (inflation). You don't have to save in some area or tax more to have more money. The problem with printing off more money is that it benefits the government as they get more money to spend while hurting the people who currently have money such as the citizens. Most governments have an interesting in some rate of inflation because it reduced the true value of their national debt. The government is trying to do themselves a favor by printing off more money so they can spend their way out of problems and pay off their debt at the same time.
