>but do that while being your own boss.

So you're prone to falling into survival bias, while also needing skills beyond just being good at your job in order to sell yourself so you can get customers to begin with.

>the initial investment in terms of capital is very little compared to "start a company and hope to break even in an year or two".

2-3 years of apprenticeship is "very little"? In addition to however much experience you need to be trusted as a business? And who's to say you will break even in a year or two?

It's very little capital investment, yes. In both absolute terms (like a few thousand dollars of school, sometimes paid for by the employer), and relative to starting a non-trade business (rent, equipment, etc).
