I'm not buying it. Judging by your daily attacks on the wealthy, it is obvious that you have a personal dislike for them. You're jealous because you're either not clever enough or hard-working enough to achieve what they have achieved.
I have several friends who make above $250K and they are not rich, especially after 40 - 50% of their income is consumed by Federal, State, and local taxes. Raising taxes on these individuals is guaranteed to kill jobs. At some point, many will decide that it is simply not worth running a business, and they will close their doors and work for someone else. This is the conclusion that I reached rather quickly when I started an IT company a few years ago.
Like all Marxists, you are an economic illiterate.
I'm fine with raising taxes on people who make over 5 or 10 million per year. I don't believe it will hurt them, and it will be necessary to balance the budget. I do not favor punishing middle-class business owners for their success. Your bigotry toward those who have more than you is disgusting and unamerican.
