Yeah one good example is what happens in labs on college campuses - 30 years ago 14 year old kids in high school would get paying jobs from labs without knowing anything whatsoever, an apprenticeship of sorts, and a lot of great scientists began that way. Nowadays, even if you have a post-grad level skill set you will be volunteering and not paid a dime, and if you don't have parents paying your rent and your grocery bills that door is closed. The work is more than a full time job, usually at least 80 hours a week these days, so taking a second job isn't an option. Even of the people I know who managed to get paying work in a lab, they are paid jack shit for developing scientific breakthroughs that save millions of lives and revolutionize our way of living... they'll make 16-24k a year, but they'll be fired if they write down their real hours which are ~80-100/week, so their real pay comes to about 6 bucks an hour... just sad. These same people are looking at paying 300/mo for their student loans for 10 years plus. What have we come to?
How can you have a family if you can't break out of poverty until you're in your late 30s or 40s? And even then both parents will still be working crazy hours. It's not good for the mom, or the kids, to have them past your 20s, there's greatly elevated risk of dangerous complications for the mom, greatly elevated risk of cerebral palsy in the kids, and I read some study where they found the lifespan of a kid is shortened significantly if they were born to a "senior" mother.
There is so much wealth in this country, everything is so mechanized that our labor produces an incredible amount of value, and yet we see so little of it, particularly during our most productive years, and when our need is greatest.
