It requires a fair amount of skill to pick a lock quickly. Someone capable could probably make more money doing something legit.

Depends, do you count wave-raking as picking? I bought a cheap lock-picking set, takes me about 5 minutes to get their basic perspex lock open. "Masterlock", wave rake opens it in a few seconds -- even my then 10yo could open it in <30s.

Yeah, like running a Youtube channel on lock picking.

Or like being a lawyer?

Or both :)

Having heard of a typical locksmith's rates, if you can pick locks well then you really, really do not need to resort to burglary.
