Of course, very few parents didn't want their kids to go into higher education of some kind, and I think for about 99% of parents with college education, their children going to college was already a forgone conclusion for them.
I wouldn't put the blame entirely on the parents or the kids though- practically every school I've seen advertises job placement numbers; don't forget about the lawsuits over law schools artificially inflating their numbers to get more students. If you're a parent seeing that, why wouldn't you push your kid into college?
In my upper-middle-income family and peer group, not going to college was unthinkable. Debt wasn't really a consideration since few of our parents were struggling with debt and we based our future expectations on their past. Then it turned out the game had changed dramatically in 25 years.
I had a couple lower-middle/upper-lower income friends, for them college was much more of a goal than a given, but also one that they were very aware of costs/risks around. But not one that didn't seem worth the upside.
From what I've read of people growing up in poverty, it's very different there. Many people check out well before the end of high school, and college is seen as something for other people that's not a realistic option for most.
Community college, especially in larger cities, definitely is underrated.
edit: redundent wording.
So, uhhh... It sounds like you got exactly the experience you're claiming you didn't get, but are blind to the alternative: That more schooling (even a trade school) wasn't the only option.
That is to be expected for young people right? So these young people rely on authority figures to give them advice, all of which beat the drum of "go to college, it's the only way".
Why do we expect these young people to be wiser then these authority figures in their lives?
