You are describing good Union work. Anecdotally these jobs appear tough to get into from family who work in various trades, in construction such jobs are tough to get into and tougher to hold onto ( eventually the work dries up as construction dwindles )

Unionized manufacturing does much better, with steady employment that can exceed 200/hr for the right work. These days you can pretty much only get such jobs via connection as they aren’t creating more of these jobs very frequently.

Source: The 200/hr figure was based on underwater welding for USN ships.
