Strange, I know many "white collar labor" individuals without "
a minimum of 4-years of university-level education".
You're correct that "blue collar labor" does not have that
requirement. In fact Department of Labor accreditation often only requires 2-years of university-level education. In conjunction with upwards of 8,000 hours of on the job training (OJT).
I know what you mean though about the ability to recruit nearly illiterate peasants from the countryside. On my last trip over seas I was impressed with the Chinese way of recruiting. Just throwing hats into the countryside with the names like Nuclear Reactor Operator, Instrument and Controls Tech, Robotics Tech, Registered Nurse, Electrical Maintenance, Machinists, Turbine and Pressure Vessel Welders, etc. I know that the GE Executive Development training program states that all of those jobs are mere button pushers. With no job being considered skilled, unless it calls for an MBA or Doctorate from an Ivy League school. It's sickening that those peasants feel they can earn more than minimum wage, no? Where's Rush?
