There are more than 80 examples outside of China or SU that we can look to for why socialism is the ideology of the inept; Cuba, Laos, North Korea, Portugal, Cambodia, India, the list goes on and does not contain even one example of success that does not involve the permission of some level of free enterprise.
Central planning. Top-down authority. Trickle-down economics. Abolition of Private property/enterprise. Public ownership of all goods and services; all of these Socialist policies have been tried and utterly failed. Especially Central Planning.
