You make a couple of the same assumptions that most people are habitualized to.

1: That a job is a prerequisite for someone to contribute value to life itself/ a place/society (see "unpaid domestic work").

2: That the point of screening has anything to do with usefulness, rather than everything to do with avoiding liability and sunk costs(training). I think a lot of the Credentialism came from the lawyered-up civil service/security screening methodology. Systematizing a process avoids making the interviewer having to make critical judgements.

"The only thing worse than doing a government man's job for him is to make him do it himself." At this point, the 50 billion dollar companies ARE government (see "income tax code corruption").

3: That people have a choice to NOT get a synthetic "job." The simplest starting point is not some minimum wage in service of 'voluntary' exploitation(adjusting for inflation, it should be $25 per hour now): it's UBI (including education and good health: think of all citizens as potential enlisted combatants in reserve).

Pay for it with sales tax/VAT and eliminate the inherent corruption of the income tax code(as well as the power it places in the wrong hands at corporations).

These all come into play under the backwards economy as we know it: human civilization is consuming and exploiting for the sake of blind Big Money wishes, rather than people prioritizing the acts of being contributors to living places and each other.
