Economics focus: Don’t look down

This is an interesting hypothesis. I suppose this also goes along the lines of people getting mad when they had to work for something, but someone else didn't.
The bottom 60% of the US population has around 5% of the aggregate wealth. That's the majority of the population.
The top 20% of the US population possess 84% of the wealth. And the curve is very steep, too; the top tenth of a percent holds a whole lot of that wealth, and it's increasing rapidly.

It's been a while since I read it, but it was quite interesting. The author presents an economic model to explain status-seeking behavior and how it affects, for example, wages. It presents a model why "super star" performers don't get paid what they're worth (He models it as a subsidy to those below them, who would leave for a different firm if they were at the bottom of the hierarchy).
I've always gone with "expressing tribal affiliation" as a good explanation. Since your vote doesn't matter, why not try to raise your status by voting in order to raise your status and signal tribal loyalties?
I don't support taxes that are "redistributive" and don't think we really have them.. to the extent that the rich pay higher taxes (which they barely do at all on a % of income basis), they're getting more value from the system.
Once people agree with this premise, everything changes. Unfortunately 30+ years of Reagan's "government is the enemy" agenda have pushed us back too far.
Actually, asking the question that way leads you to another answer; they believe the policies will benefit them in the long term. Some people may observe, for instance, that an extensive welfare state may have an apparently economic beneficial effect in strictly monetary terms for those on the bottom but that it has a very corrosive effect on almost every other social measurement. Or that the growth penalty you take in supporting the welfare state is complicit in itself keeping the welfare recipients poor enough to need welfare in the first place. Or an awareness either conscious or otherwise that a democracy can't survive long with the majority voting themselves benefits from a minority, regardless of what other arguments in its favor it may have.
This paradox is better phrased as "people are voting against what I think is their best interest, what gives?" in which case the answer immediately becomes obvious: They don't agree about what constitutes their self-interest. And given that they are where they are and you aren't, perhaps one might take at least a moment to consider a motive other than stupidity or error.
