In most instances it isn't that the wealthy are against paying more, it's that they're against being forced to hand over more money to a goverment that squanders it and spends it without any form of accountability/responsibility (re: the stimulus).
If your teenager came up to you and said, "give me $100", you would ask them what they were going to spend it on, and give input whether that is a good choice. That is what the wealthy are asking for.....before they just hand over more money to Obama/Congress to waste, they want to know what the money is going to be used for.
Makes perfect sense.
