Traditionally, being self sufficient enough to move out of your parents house and live on your own was considered a major, basic, and early benchmark of growing up, adulthood, and success. Sort of like taking your first steps, it was just considered a "bare minimum" benchmark.
That impression, the idea of moving out on your own being the bare minimum start to being a successful adult, has not kept up with the modern age and the economy we've grown up in. The idea that anyone should be able to move out on their own came about in an age when a single adult working a basic job full time could afford a house and support a family on their income alone. That just is not even close to the case now, but some societal memes take longer to change than others.
I've been looking for rentals lately. Every inspection has dozens upon dozens of people show up. Rental vacancies are at a tiny fraction of a percent. No landlord will take someone if the rent will cost more than 30% of their income. To qualify for a studio apartment it takes almost double the median wage.
I hate it so much. I've budgeted so that I know I can afford these places on my income, I have a significant pile of savings and a stable job. I have been looking for a place for six months and been rejected from them all.
I've given up. Even if I could get a place it'd be cheaper to pay a fucking mortgage.
