The Alternative Minimum Tax primarily affects upper middle-income people, and usually does not affect those at the very top. It's typically people making $200k–$500k who pay the AMT, especially married couples. These are often young people with careers but no real savings who might be trying to buy a home or start a family. Instead of getting a tax refund every year, many of them find themselves with $10k bills.
Establish a 90% tax on bonuses for bailed out bankers
I prefer overall compensation limits for bank executives. When we bailed out the auto companies, the government negotiated limits on union compensation. We should do the same for financial sector compensation to ensure that the public is protected against the tendency of bankers to greedily and dangerously push the envelope in search of short-term windfall profits and compensation. A 90% tax on bonuses will simply shift compensation toward salary. That might be a good thing, but it won't raise revenue or keep bankers from making millions through behavior that puts the financial system at risk.
