This is paired with the lack of stability in employment seemingly across sectors and general economic uncertainty.
I hear concerns like the following, across social groups:
"I'm 'paid well' but live in this dusty old apartment building that's, at most, 700 sq ft."
"If I lose this job, what's the likelihood I make the same amount to even afford this? How long will the job search take?"
Few other things: I pay more for car insurance now than I did when I was in my early 20s, despite driving a far slower, more pedestrian car. Food prices are laughable, even rent far out from major employment centers is much much more than it was even in the late 10's, etc.
I think all of these are major factors that almost noone is immune from.
Almost everyone I know will express some sort of exasperation and lack of security related to the above. These are not the conditions that motivate people to have kids.
