@engineer,
I agree with your stance on the wars, however, it would be incorrect to say there are only two major differences between now an 12 years ago, war and decreased taxes. Your are excluding the fact that the government now spends twice as much for pensions, health care, transportation, and welfare than it did 12 years ago. Spending is absolutely a component of our fiscal issues.
Your responses indicate that your are in favor of higher taxes. But how does paying more taxes really create more revenue? Sure, the government would have more revenue from the people's income but then you and I and everyone else would have less money in our pocket, causing us to consume less, which takes money away from the government. It's a wash. Although I think the taxes could be done more effectively, I do not think it's one of the two major reasons that we have a deficit.
