I don’t think that is true. Ubiquitous access to free or low cost education is what makes this possible, and I certainly don’t see those kinds of businesses in towns of 50-100k people in the USA. There are people that are capable of that kind of work, of course, but they are employed by x corp or do contract work, and they are not competing with the cost of replacement consumers devices, since their rates would have to be > 150 an hour to stay in business.
