Anyway - the problem isn't that wealthy or poor people believe the kind of garbage that comes out of TED talks, it's that they fund it! The wealthy buy the books, the wealthy go to the conferences, the wealthy give them seats on their News Media channels or feature their talks prominently on their news websites. The wealthy run the Universities that give people their doctorates that legitimize their wacky capitalistic ethos. The poor can repost a TED Talk to Facebook, and that's about as far as their power to influence goes. The truly poor do not even have the money to buy 8 plagiarized Fareed Zakaria books.
It's worth mentioning, also, how little you need to make to be "wealthy" in America. With generational wealth playing such a big factor in people's finances, merely NOT having mountains of debt or being in good health are game changers. Throw a $100k salary on top of that (that's more than 75% of people make) and you're living large enough to buy a Fareed Zakaria book every hour for the rest of your life if you so needed.
