I don't know where you got those numbers. For the past 20ish years or so, the rallying cry in American politics is that everyone needs to go to college in order to have a job.
It's only recent that the left is pushing for jobs that don't require college degrees.
I also haven’t heard of a change in the narrative where jobs that don’t require degrees are pushed by the left. If anything I see people calling for higher washes for low end jobs but that’s a separate issue entirely.
