Candy, good advice. My advice isn't nearly as good as yours because it isn't very practical, but here goes:
Young people should time travel to when Candy was a young adult. Tuition at a state college was, what, $500 a year? (Maybe $2,000 in today's dollars.) Now it's utterly impossible to "work your way through college." When was the last time you heard that phrase? It's a joke now, isn't it?
And back then shortly after they graduated from college young people could probably buy a house. Of course now those fortunate enough to graduate from college wind up with student loan payments making a mortgage undoable. So no house for you!- unless you have family money.
Another good reason to time travel, especially for those who didn't advance their education, was that blue-collar wages were so much higher back then. Thirty years ago we had a much, much higher federal minimum wage in today's dollars and many more union jobs with higher union wages. Didn't belong to a union or work for minimum wage back then? No matter, those higher wages put pressure on other employers to pay higher wages, and you were probably a beneficiary. You know, a rising tide lifts all ships.
So like I said, Candy, good advice. Just realize that as a group, young adults today have a much tougher time than your cohort. Your generation left behind a real shit-show, and even though I'm one of them, we can't bury Boomers fast enough.
