This article resonates with me on many levels. I went from below $10/hr to 5x that and never experienced anything in between. The struggle is huge, and I keep having to look inside myself to figure out what "my people" is supposed to mean.
A huge different that's obvious to me is the language we use. I often wonder why no one's mother didn't fill the these people's mouth with dawn liquid soap and slap the child silly, but then I realize that honesty wasn't a life or death situation for them. I'm often called brutally blunt, but really, I'm very tame compared to most people I grew up around.
As a real example, we often get articles on Hacker News that discusses the best way to hire, best way to land a job, best way to self-learn, and so on. It took me years to realize that these articles were all shaded in a heavy fog of bullshit, and it took me many years to realize that the posters who upvote and share these articles are not only aware of the heavy fog, but are able to read though the fog. If I was able to go back in time and tell my autodidact self on thing, it was to learn about bullshit, and it's something I always advise those who trying to self learn.
