No. There aren't enough "rich people" to get a politician elected. Most of these things in the tax code are one small chip at a time to make some ordinary person favor a particular politician. Including things like "Roth IRAs" The fact that they have unintended consequences is another story.

I don't think the fact that Peter Theil has a billion dollars hurts me in any way, and no I'm not some unrealistic person who thinks that I, too, can be a billionaire! Only a petty person would be disturbed that someone else has more money than him. It's not a zero-sum game. The fact that there are some outlier billionaires doesn't hurt the ordinary Joe.
