This may not be a problem inherent to capitalism, but it certainly is a problem caused by the capitalism we currently have (by which I'm specifically referring to the US, but it may apply more broadly elsewhere).

And the government's failure to adequately regulate the market is due to the right. The party that claims government doesn't work has repeatedly - for generations - run on this as their platform, and when in power, they ensure it doesn't work by continued regulatory capture and gutting of consumer protections.
