The problems of wages and demands are closely related. You can either choose wages that are too low to live comfortably, or responsibilities that are too high to live comfortably. Either way, human needs are fundamentally disrespected.
No.
There are jobs which pay well that offer good quality of life. It's up to the individual to choose and pursue them. I can say from experience though that people get caught up in the social pressure and stigma associated with having less, or not earning as much, and end up taking on more than they want - which leads to stress and less happiness (but more money, which doesn't solve that). Corporate culture, in many cases, especially large companies,
assumes that you want to move up the ladder, get more responsibility, make more money, take on a "leadership" role, etc. etc, and there are so many people that buy into this, and people that encourage it, or people that exhibit choice affirmation bias and want you to make the same mistake they did, that it's hard to resist the social pressure. There are some environments, like law firms, where the career path is up or out. You either make partner or you get canned, no room for longtimer associates. The assumption will be that you want to make partner, and if you choose not to, the new assumption is that you
couldn't make partner. These kinds of up or out situations are not the norm though, but it's still hard to resist the temptation to take more money. Promotions are always a good thing right?
I think that we're on the tip of this realization socially.
A lot of people would take a pay cut to work from home:
That's a mixed question, some of it is money vs. money, but a lot of it is quality of life vs. money. And of course you'd never expect to see that number hit 100% partly because for some, the quality of life is assigned to
not working from home.
Getting promoted beyond the perfect mix of quality of life/income is easy to do, and it's something that we, as a society, don't raise enough awareness around. It's also really hard to judge. There are some posh jobs out there, the trick is getting one, recognizing it, and not letting yourself get tempted out of it.
