Yes, but when those with capital start to restrict markets is when the economic system changes.
There is nothing wrong with wealth. You can have as much as you can. Just allow others the same opportunity.
Regulation, which many think of as being “socialist” is mostly generated by capitalists manipulating politicians, (and in turn the system,) to protect their own wealth.
If you have a lot of capital you can pay what more regulation demands. However a smaller player, or newcomer, to the market might have a hard time overcoming those requirements.
Which is why the rich love socialism.
