You put the /s, but I don't think this comment is inaccurate in any way. Some people really have enthusiasm for nothing but making money. No hobbies, no interests, no friends, no other goals.
As long as those people have morals, what’s wrong with that?
Since it's unavoidable, the best next thing is to design a system which takes greed as an input and outputs productivity. That system is called Capitalism and that is why it always wins.
