The question to ask here....are there any anti-capitalist pipe-fitters or HVAC technicians in America today? I don’t think you can find a single one.
I also don’t think you can find any plumbers with anything other than house, credit card or car loan debt. Unless that guy screws up and marries some trophy wife...the typical plumber ought to be able to retire by age 60, and have a decent income in his older years.
Even Nixon’s plumbers were Capitalists.
