You asked where our wealth went and I told you. I can't help it if you don't like the answer. The wealthy in the USA up until 1984 had a tax rate of 50% and more importantly a capitol gains tax rate of 50%. Those rates are now 16.5% and 15%. That's alot of money the gov't does not have.
The other problem is our defense budget. It is totally out of control but no one seems to have the courage to challenge their budget. We spend more money on defense than the rest of the world combined.
