The article literally admits is first point was misleading.

My carpenter buddy sets his own schedule, spends his time pulling his camper, works extra when he wants to, floats in and out of his union asks (exploiting their rigidity).

He’s been at it for years, so he’s a qualified instructor for anything he can get his hands on, even esoteric stuff like pouring concrete for nuclear facilities.

His job is hardly comparable to an Amazon driver, like this article conflates. Bro makes more than an equiv exper and age software dev, but with no glass ceiling.
