I'm going to guess it's because most people have much more stressful lives and are too busy to be be bored (busy trying to figure out how to provide for themselves and their family, trying to get out of debt, etc). Also, most people do not have office jobs where they can drink coffee at a desk and listen to podcasts all day; most people have manual labor jobs and office workers are considered to be higher up the socio-economic ladder. So, the post is here to make fun of privileged white people who have a good life complaining about mundane things.

Yes, it's mildly racist. There are, of course, many white people with low-paying jobs, and many POC with good paying jobs; but there is some statistical truth in the medians.
