The problem is getting and keeping people in power who actually want to reign in capitalism.

But then that's not capitalism. Capitalism is making as much money as possible unrestricted as much as possible. If you start doing things like putting a maximum wage in, or taxing the highest earners and giving back to the lowest, that's socialism.

But now in almost every country, the capitalists are the ones making regulations. They're not going to do it to themselves.

Which is controlled by those with capital.
