The real issue is that a few people have accumulated a lot of wealth and property, and they use it as a tool to extract even more money. It's basically the late stage capitalism money vacuum hoovering up everything. In the past the only levers we had against this were breaking up firms and enforcing anti-monopoly and preventing capital from even entering certain parts of our economy. We could, for example, ban private equity companies from buying houses and healthcare companies, break up national monopolies into regional companies, and eliminate a lot of the consolidation that has traditionally enhanced the bargaining power of the company owner against the employees.

In the short term it would make a lot of stuff less efficient, but when people talk about "efficiency" they really mean driving costs down and driving income up. So we really don't want an efficient capitalist economy, we want a capitalist economy that is just efficient enough to meet our needs while not being so efficient that a few people can exploit that efficiency and run away with our things.
