> Most of your entry-level jobs were supposed to be for highschool and college kids working part time.
This is some soft language hiding some bad assumptions.
"supposed to be" - what does this mean? because it's a lot more interesting...low skilled jobs, are probably what we're going to be talking about. However, it's not the 1950s anymore. eg Staffing a movie theater is not a part-time job (which you would know if you have ever worked one), even post-covid.
Targeting for graduates (or current students) is reserved for economies like college towns, historically. Those places have also experienced wages rising noticeably over, at least, the last 2 decades. Industrial and metropolitan areas don't have enough "school labor" to staff all the unskilled positions, regardless.
> Not all jobs are intended to "live" off of
If you have a fulltime job, the minimum wage is intended to allow you to survive^. The main issue is that places with fulltime positions open to unskilled labor, have living costs that outpace the minimum wage...all the way out to the most rural of US towns. The financial guidelines for employees from McDonalds, Wallmart, etc are telling.
^Claiming that jobs that pay minimum wage and only allow working 30 hours a week, aren't intended to "live" off of, is cherry picking exploitative employers. This is not compelling, nor the common case, so we can focus the discussion on the issues that the majority of the economy deal with.
