That would be a straw man Neoliberal idea. The Neoliberal idea is about privatisation and competition, but well within a regulatory framework.

Venezuela is a democracy and it is a mixed economy too. Just like China is also a mixed economy. Great gun control, tho. It's more skewed towards the state ownership and command economy side than China and the USA. If anything, the command economy idea is dead. At least it should be.

Correct about the USA, though. It is also a mixed economy.
