I wonder how he would react if I would mix up "soviet socialism" and "socialism"?
This mix was tested already. Hungarian socialism aka gulyáskommunizmus worked quite well, it was the most advanced economy in the eastern bloc.
Care to explain how Hungarian socialism is any different from the mix we have today?
Hungarian socialism was socialism with limited free market economics. Today we have social liberalism with limited free market economics.
And I don't think any of these "mixes" have ever worked quite well.
