The alternative is to fix rampant abuses we see with highly concentrated capital accumulation that results in a proxy of many unchecked powers in private and increasingly public spaces. There's lots of paths being pursued to curb this.

Antitrust legislation and most business regulation exists because of abuses that naturally arise, I don't know why the narrative of continued deregulation solves these problems--regulation is pretty much the only way to leverage the benefits of capitalism without allowing it to become yet another oppressive system over the majority of society where the oppressors just become a class of the ultrawealthy. My opinion is that were well on our way down that path as we see increasingly less value add back to society and a lot more value capture strategies instead.
