I don't think working a boring high paying unfulfilling job inherently makes one happier than "saving the world", but having financial security and good work/life balance is certainly superior to working long hours, living paycheck to paycheck, and flirting with poverty.
But I'm convinced that one of the keys to happiness is to live a life that plays to your strengths. If you have a natural aptitude to problem solving etc then you could become a really good engineer, or you could become a mediocre violinist. Which is going to lead to a more fulfilling life?
People are born with natural talents. We should be encouraging people to do what they're good at, not telling them they can do whatever they want to.
The flip side is that the economic contribution of a single employee becomes vanishingly small, affecting the salaries, or rather what you can buy from them.
I agree with you that building your life on top of your natural strengths is the most fulfilling way of spending it (having done so myself), but I think these days it is extremely hard and is only possible if you manage to start your own business and grow it to the point where it can pay your bills.
I don't think most people are against doing what they are good at (or even, what they like), it's just that discoverability is poor and in a lot of cases the most important thing ends up being a certain brand of social or political skill, and not the other secondary skill you might posses. For people to play to their strengths, we need a society that can detect and nurture those strengths, and I don't think we have that right now.
How much money would you pay to free up 50% of your time? I decided that was worth $70k, going from a $100k job to a $30k job while working on a beach.
I have friends my age trying to retire early which means they spent their 20s and now onto their 30s working their ass off which aren't the years I'd be so eager to throw away at work.
Once you have children, then you need to be in the better school districts, in the area with better income security, hence you’re now competing with other parents also trying to secure as much as possible for their children, and on the treadmill you go.
