I do believe in the value of an educated populace not just for jobs, but for democratic and civic strength.
There is some nature to consider, not just nuture, I guess.
I graduated in the top 50% of my high school class and had a 3.2/4 GPA at a state EE program. I hear about high school kids studying 3 hours a day, I don't think I ever studied much more than 3 hours a week. Definitely not stellar academic credentials.
I ended up entering an md phd program where I washed out after 5 years. Fast forward a few years (20...) and I have my own company and will make about $800k-$1M this year.
Yet at no time was I unhappy, even when I was digging for change out of the couch to have enough money to buy food. I remember savoring the ridiculousness of the situation and reveling in it. Yet I'm no happier now than I was at that moment.
Part of life is figuring out what truly makes you happy. For most of us it ends up being bringing happiness to others in some way, not achievement and material possessions.
One thing that became abundantly clear from watching my kid go through the college process was that "better" is highly student-dependent. I had a really really great time at university but was happy that my kid didn't even apply there as I think he wouldn't have enjoyed the experience and would not have flourished; in fact he did end up going to a school I could not have handled.
Assuming you enjoy your job at the "big 5", is anything wrong?
(Not to say that it's always useful to reflect on the path not taken once in a while in case it provides insights for the future! But tiger parenting -- as a recipient of it, though my parents tried to tone it down -- is predicated on there being a "way", which ultimately there isn't, at least in the USA).
Less wasteful, less disappointment at not being happy all the time.
