Please! Try having a few kids and living in a desirable metro area. I didn't stop worrying about money until my salary was twice that, and my wife works too.
So many sayings about financial happiness seem written for single people with no dependents.
The increased salary of an expensive area does not normally compensate for the increased costs. It might if you are content with a studio apartment and you put most of your income into a retirement fund that you will spend only after you leave the area. You're in deep trouble if housing is a significant need for you.
It's like this: salary goes up 50%, and expenses go up 200%, so you lose.
70k, with just a single income, is perfectly fine if you live somewhere cheap. You can easily own a home and raise a family with that kind of money. I know people who manage that on far less.
Good for you. But I really wasn't trying to say how much people have the right to earn, just pointing out that likely there is some upper limit where money alone does not bring much additional happiness. Obviously people have different priorities, life situations and preferences. I just wanted to point out that money can't be used as an objective measure of happiness or professional success in the most generic philosophical sense.
I can totally see how a metropolitan location would increase life satisfaction by providing a rich selection of entertainment, cultural venues and restaurants (i.e. experiences).
Also, the money:happiness ratio has been investigated quite a lot, and as I recall it never really peaks, it just becomes less of a factor.
