You could be right about where the money goes, but I think people's minds are more concentrated these days, and we know
that training, infrastructure, technologies for the 21st century - all are areas of necessary investment. This Intertube thingy we are conversing on was a direct result of government investment in ARPA and university programs, and it has given us not only a pretty sustained level of income and production with a couple of bubbles and busts, huge improvements in communications and democracy, and allows a lot of business to make profits they could never make without it. So government investment does not always go to useless things...
As far as incentives and trusting the wealthy to do the right thing - if that was true the tax cuts and easy money of the Bush era should have led us to prosperity. Instead lots of wealth and millions of jobs moved to other countries, hurting us badly. The easy money was invested in much more housing than we needed, along with huge investment funds leveraged to heights that would have been unattainable without the complicity of government officials (i.e. active lobbying to remove regulations because, of course, we can "trust" all these good people to do what is best for us - for example, Goldman Sachs and BP).
Take a look at this post
link here.... It would be incredibly selfish and naive for anyone to think that their own effort is all that is responsible for the advantages they have reaped from the work of everyone else, and I don't think your post meant to imply that. I don't deny that they are smart, and nice, and have provided you a position you like. But they didn't do it alone, and you should be thankful for many others who made that possible (and I am sure you are).
So what is a fair amout for them to return for the privelege of using their smarts to gain as much as they can from the system? I don't think 35 to 40% is too much, especially if people have been able to gain much more than others. It is a fact that when taxes were relatively higher on the wealthy than they are now most people had a higher standard of living than now, there was less poverty, a far higher number of children didn't have to depend on school lunches just to get a meal every day. When those taxes were cut deficits, income inequalities, and poverty all increased.
So I am in favor of higher taxes on the wealthy and a large stimulus program along the lines of about $1.3 trillion. (We set aside $14 trillion to help Wall Street maintain billions of dollars in bonuses, (smart people who work hard), so I don't think 1.3 is too much to spend on Main Street.
