@IRFRANK,
Well, this is a first - I finally disagree with you, IRFrank.
All of life is not about wealth gain, though it seems so, and is very useful, I take it.
I agree that if one has children, this matters, but how to get there isn't all that simple.
I disagree that study is about money, in the end.
It's probably true that my interest in knowledge (not that I am so knowledgeable, but I'm curious) is a benefit of my early years in the middle class - before my parents were in trouble - and a benefit of getting into a nearby university that didn't charge tuition, pre Reagan.
It took me five years to get through my BA, working and riding buses many hours, and also changing majors. After that, I took extension classes in art, many units, expensive. Then I took four years of classes in landscape architecture (not a degree, it wasn't a degree program, but required a degree to get into, also costly for the courses), two years of apprenticeship, and passed a national exam.
There are some famous landscape architects out there with more prepossessing qualities than me, but it was a field that was very satisfying for me.. I was happy.
