Reddit is a cesspool of largely young, wanna be socialist, liberals around the globe. So yeah, their definition of "rich" is going to be very skewed.
There are some sub-reddits where you can avoid this, but the majority of the "common sub-reddits" and the front page is inundated with nothing but deluded liberalism.
It is truly astounding to read some of the comments that ALWAYS percolate to the top, and realize that these people truly believe it. As an example, I just saw something where the general consensus was that the Republicans were guilty of having targeted the schools and school board positions for the last 60 years. Something that is very easily proven to have been the liberal left, but they believe it. Because Vice, CNN, or some other even more flagrantly slanted "news" source printed an op-ed that said so.
It really is the definition of an echo chamber.
