The reason it’s relevant is that most working people do not earn salaries, they earn hourly rates. I’m a welding engineer earning a salary, working with maintenance men and welders and operators who all earn hourly rates. Every company I’ve ever worked for has both salary and hourly and also an HR department.
The situation you are describing does not align with the vast majority of working people’s experiences.
Simple and easy are not the same thing. Sure, enriching uranium is simple, you just centrifuge it so that the heavier, less stable isotopes separate from the bulk. Simple.
