I guess what I was hoping for, when I sent them off to college, is they would “learn stuff”, increase their capabilities generally, along the lines others have suggested, and have a socially, extra-curricularly and academically fulfilling life there that would serve as a springboard for same subsequently. In other words, to thrive there, as a coccoon, and to bloom into a wonderful butterfly. Probably after knocking around for several years afterwards, as many liberal arts majors do. In an ideal world they would identify their [initial] life’s vocational goals early in college, conduct themselves accordingly. go for it and get it, so there is no struggle afterwards. That’s something I might have fantasized would happen, but did not necessarily expect. It’s easier for the kids that decide early on "I want to be a [doctor, lawyer,architect, Indian chief,…] . but lots of liberal arts majors don’t know that.
So anyway one can hope for not so much a monetary ROI but a return function where the input is money but the output is a complicated “happiness” utility function of which money is just one component, weighted by that kid according to his/her own personal weighting system. But someplace in there should be the basis for them to achieve an economic “floor”- for them to move on in the world as self-sustaining adults. That basis doesn’t need to be a degree in accounting or something. It can be a group of abilities that will be recognized by someone, someplace, sometime, hence realizing the floor, at least. But I don’t want them to starve, for sure. I do want them out of my house, and out of our pockets. But it’s more than money; I want them to have a happy life. However they define it.
On that basis, my kids have not hit the “home run”- decided exactly what they wanted to do with their life during freshman year of college, conducted their entire college career accordingly, achieved their goal immediately, are already retired and bought us a nice new house, …(ok I’m getting carried away).
So to answer OP’s question I don’t think our investment in D1’s college was “worth it”.For her. As it turned out. She didn’t thrive there, to her full potential. What she’s doing now is partly in spite of that experience IMO. It was all on her own, and the innate abilities she came there with.
D2 has blazed her own path, right out of college. she had many opportunities during college, got a job she would not have had if she’d gone anyplace else, leveraged that into opportunities in totally different fields in a totally different part of the country. In addition to the skills she developed there and her own innate abilities, I’m pretty sure her college name helped her get some of those subsequent opportunities. She has not found her [initial] “true calling” yet, but she has proven that she has the tools to survive on her own. I think her college was worth it.
Last kid is just graduating, we’ll see.
