Previously, the general rule was that a business was there to produce a good or provide a service, and the profit they made (if any) was the reward for that. There were some businesses that acted much more greedy, but overall it was clear that this was how business worked.

Now, the rule is much more that a business is there to make as much profit as possible, and the good they produce or service they provide is purely a means to that end—and, in many cases, largely an undesirable one. Again, there are still some businesses that operate based on the older philosophy, but overall this is the prevailing atmosphere.

This is what I would describe as the dividing line between "capitalism" and "late-stage capitalism".

As for an end to capitalism:

"We live in capitalism. Its power seems inescapable. So did the divine right of kings. Any human power can be resisted and changed by human beings."

― Ursula K. Le Guin
