I think it's very easy to start a failing plumbing business. I think it far less accessible to start a plumbing business that competes with a FAANG salary.

Put another way: how many people do you know who started their own consumer-facing, bootstrapped business, of any kind and who take home $3-500,000 as CEO? My answer is, like, two and they're both lawyers who didn't start making that kind of income until their mid thirties.

Edit: It would not, at all, surprise me if even in the trades the most common path to business ownership was to take over someone else's already existing business, which would I think cut even further into this point since it would mean the most common path to entrepreneurship is optimizing employment in a small business context.

I think getting a FAANG job is difficult, but for the median 30 year old (who has around $5,000 saved up and limited or no external safety nets), starting a business as your primary source of income is a really good way to bankrupt yourself and not much else, and valorizing that path is actively harmful.
