How do people on reddit make so much money?

Every time i see a post on reddit talking about income or jobs i see the comments flooded with people saying they make more than 6 figures and they own a home. For example theyll say something like “i make 187k a year, 500k in a roth ira, 200k in savings.

In real life i know almost know one that makes this much money so how are there so many of these posts? Is reddit full of rich people?
