There was a thread about data-centers hiring trades for $$$ ad everyone was cheering and anyone who asked tough questions like "why is supply so inelastic and is that a good thing?" got screeched at by ideologies. He's poking fun at that.

The "(contractor)" bit is because it's usually not the guy doing the actual work making the big bucks. That guy's making marginally more. It's the guy billing that guy out who's seeing the lions share of the huge price increases.
