Good doesn't mean moral in this case, it means valuable. Capitalism, or whatever the fuck we have right now, doesn't create much real value, but instead it creates a lot of fake value that we just proxy.
And I say "or whatever the fuck" because, as you point out, it's not really capitalism. And maybe it never was - after all, the US Golden Era was when we had the most central planning, the most social services, and the highest taxes.
But everybody right now is exploiting one teensy little flaw of the economy - humans don't live very long. There's no reason to make stuff good for later when you can take a cash advance and get rich now. Everything is always someone else's problem.
I think one fun case study is superstar CEOs. They're so highly desirable, and they work 5 years at a company and "turn it around" before moving onto the next. But if you look at the company after they leave, it's in shambles. And yet, they are the most sought after CEOs. You don't want the Arizona Green Tea guy, no, you want the guy who ran Chipotle into the ground. But hey, at least he increased their stock price for, like, a little bit.
