IMO the saying is more about how when you eliminate the struggle to acquire wealth, there's less meaning in your day to day life. I'm sure folks like Musk and Bezos for example are looking for something that makes them feel purposeful, like going into space. Not necessarily trying to enrich the lives of others.

I agree though that not having to worry about bills or putting food on the table is it's own kind of happiness. I think there's a healthy balance.

With luck, it buys a state in which we can find happiness.

Is it possible to be happy without money? I'd say it's only possible for extraordinary people, not for the majority of us.

Is it possible to have money and still not be happy? Of course, many people have money but still feel empty, lonely, misunderstood, apathetic, bitter, regretful, etc. And many people have money, but they cannot be happy because their health is bad and it is not solvable, not even with their riches (e.g. treatment resistant depression, terminal cancer).

I'd say, for almost everyone, money is a necessary condition for happiness, but it is not a sufficient condition.

I have money and am miserable lol. Congrats tho
