Are you really claiming that the hundreds of gigabucks (and rising) the federal government spends each year on debt service doesn’t matter?
Will it ever matter?
If so, when?
yes!
The only reason they tax us is to control us. Taking half your money away doesn't let you get ahead very fast. Why save if half of your earnings get taken away?
If the economy does tank the borrowers aren't left holding the bag. The people who own the bond certificates get hurt. That's basically rich people and the Chinese government.
The farms don't go away, the trucks to ship the food don't go away, the water doesn't stop running. So stop worrying about the deficit and worry more about the borders. The invasion will kill this country faster than the deficit ever will.
