While true, the majority of them (in terms of humans, not dollars) are merely capitalists of the "temporarily embarrassed" variety.

The thing about the 1% is that they're a really small part of the population. Less than 5% of all people are in the top 1% richest people. Extremely rich people may be overrepresented in EA, but I doubt they are overrepresented enough to beat all the prole EAs in a fistfight should they all suddenly become militant communists or something.
