I truly feel bad for new graduates who are entering the job market right now because they're 100% set up to fail. Unemployment for new grads is 6.6% right now (and even almost 6% for those a few years out from college). 

The irony is that students did the "right" thing by going to college and getting degrees. Many even chose "safe" degrees like business and computer science and they're being met with one of the worst job markets in modern history.

Hiring in tech and business has slowed down tremendously, people are being laid off and quiet fired, and many people of retirement age are holding onto their jobs a little longer. 

Gone are the days of truly entry level jobs because nowadays companies are hiring 3+ years experience as their bottom level. This has led to underemployment-- where students are getting jobs that don't even need a degree to pay their bills. And they have side hustles which they're further penalized for in the workplace...

People will blame it on "kids these days..." and the Gen Z stare, but we all should have some empathy for younger generations. Yes, I know the walk to school was uphill both directions for you but at least your $1 could buy 4 times as much.
