Legitimately curious, are you your own boss or do you work for someone else? Because you're voicing some very dicey opinions here. 
Some yeah, they are. But a lot are not. Many of them legitimately cannot pay $20 an hour - there are a large number of chains in real trouble right now. Mom and pops have been hit equally hard. Cost of everything is going up. Everyone recognizes inflation is a serious problem - but that gets into politics which is not allowed on here. I do think you're being overly aggressive here.
They don't, no. But if they do take a job then they do have obligations, which frequently are fulfilled poorly or not at all.
Yeah, living at home playing video games on Twitch and trying to be Tik-tok or Instagram famous instead of actually setting foot in the world.
This actually is a valid statement - very difficult to achieve but definitely one to go for if you can.
Maybe because many of them are offered by non-profits who have tight budgets?
I am using it to paint the majority of employers as malicious, which is exactly what I believe they are. They want you to think that they can't pay a $20+ minimum wage (with current inflation this is still too low to be honest), "so here work for $7-$12 an hour, part time, no benefits, while rent is several thousand dollars per month. What, you don't think this is enough? Well everyone else does - you are the problem." It is gaslighting, but on a societal level

If gen z isn't interested in this sort of work, then that isn't their fault, for they have no obligations to take it.

They must be finding some better way to get by

If you have a skill - and it does not need to be a strictly practical one - you can, with some work, pursue an entirely independent career and be your own boss - and I do recommend it, younger people.

It is also an unfortunate fact that in the world we live in right now, zoo and biology themed careers are not likely to make you rich or well-off.
