That's not unregulated capitalism, it's mixed regulatory, with regulatory capture capitalism.
Unregulated would mean that I could set up a lab in the basement of the abandoned farm building next door and produce untested insulin cheaply enough to undercut the whole market.
There are semantic arguments that run counter to this but we absolutely could have a system that resembles our current one but with regulations for the truly insane exploitation.
Yet there are millions out there who will defend this by voting for it although it is against their own interests. Then they blame it on those who want to stop it.
