Most middle earning jobs don't need hard skills anymore, so most of employees gradually lost them over the time (and not the opposite, like a muscle). The gen-Z is additionnaly often missing the most basic soft skills : basic, social skills, punctuality... or even coming to work at all.
So we are gradually building a generation where about two-thirds of people have... no more or almost no skills whatsoever. Can't change a wheel, can't swap a breaker, can't replace a tap, can't do more than basic IT-assisted tasks in a predefined process. More and more youngs must try hard to get their driver license, and so city dwellers conveniently skip it (but a good thing in the end). To the point that basic maths are a thing of the past for them. Perhaps 10% are currently able to write this very comment. Let's not even talk about financial education at this point, more than 60% fail at giving you the right amount of two years worth of an account interests.
I can witness that even business holders are gradually losing skills at running their own businesses those last two decades. Their skill in the differents subjects they must address all day long are almost all declining, even their core ones. They don't want to make longer work hours anymore than their employees and want to "Netflix and Chill" like everyone else.
Remains about the 20% skilled, but I have the feeling that over the last 20 years their portion is progressively shrinking. Lack of forecast made health pro number dwindle, "true" engineers (mechanical/electrical/civil) are harder and harder to find since a non-negligible part of them leave the country after completing their studies.
Are we going to make Idiocracy a reality sooner that expected ?
