It isnt actually liberalism I dont think, because to implement what I just mentioned, you would at the very least need to seize a lot of what it currently considered to be private property (that stock and business ownership), and distribute it in a way that the person possessing it does not have the ability to freely buy and sell it (else people would just sell it off for one reason or another and ownership would quickly consolidate again). Liberalism, as I understand it, has an emphasis on personal property rights that would find such a policy and later restriction on business ownership objectionable.
