More time off would make me happier. I'd give up $10k/year for it. $90k/year is enough money. Besides, few pleasures compare to spending quality time with your loved ones.
So now we have two pieces of anecdotal evidence, worth exactly twice as much as one (2*0)
So do it. Do what makes you happy. If you aren't happy working or you don't get enough time off... change the situation. But don't spend a bunch of your life unsatisfied.
The vast majority of Americans simply do not have that choice. They can't go to their boss and say, "hey boss, I want to take a 10% pay cut and get an extra 2 weeks off." American work culture simply doesn't allow that.
Any smart boss with decision making power should instantly give workers an additional 2 weeks off for a 10% pay cut. (Assuming the workers work more than 20 weeks a year and their duties can be taken up by someone else). It's pure profit at that point.
That aside... there is always a choice. Don't ever think otherwise. You don't have to stay there. You don't have to drive a nice car. Always a choice. It's just a matter of tradeoffs.
I am actually a freelancer, my example was not of my current situation. But while I was employed it was very hard (I didn't manage to get it despite trying for a while) to get a job as a developer for less than full time regardless of salary.
Anyway that wasn't the point, my point was that stating your particular preference doesn't really add much to the conversation.
