I see it a lot like obesity. Too little is very bad. Too much is also bad. But there's nothing to flag when you have too much.
You see people here complaining that they can't go from $500k to $600k and everyone says that they're being greedy. But the dissatisfaction is a lot stronger at that range, and it only goes up when people become millionaires.
I think it's quite important to check that you're eating because you're hungry and not out of habit/greed/pride.
Seems to me that this is an effect of selection. Why are people not satisfied with having million dollars? Because the personality type who could become satisfied with having million dollars, would probably also be satisfied with having half million dollars, so they are unlikely to ever have the million dollars in the first place.
People who want "exactly one million, not less, not more" are less frequent in population than people for whom no amount of money is ever enough.
