If AI destroys white-collar jobs, blue-collar jobs will fail too

There are claims that when white-collar workers are phased out,
blue-collar occupations, which are relatively slower to replace, will become promising.
But they will both collapse due to oversupply.
As the reduction in white-collar manpower worsens the job shortage,
people will flock to manual labor.
Currently, the number of self-employed individuals is plummeting,
but the supply of delivery workers has steadily increased,
including part-timers, due to platforms and increased accessibility.
Since the golden age of delivery workers during COVID-19,
delivery rates have been slashed and have become practically worthless.
It is the same for all physical labor occupations.
Oversupply occurs starting from those with the lowest barriers to entry,
and even fields requiring relatively more skill,
such as plumbing, electricity, and hair styling, are becoming saturated.
Fields with licensing restrictions, like professional occupations,
will likely hold out longer (in the end, doctors are king).
Anyway, if white-collar jobs are gutted by AI,
will it be a blue-collar golden age? No, oversupply will occur,
and they will fail together with bottom-tier wages.
If you doubt this, ask an AI.
Paradoxically, the golden age for blue-collar workers occurs
when white-collar demand is high, and when people
socially avoid blue-collar work and hold it in low regard;
that is when they can actually command a fair price.
