(When tired of mass starvation, the strategy is to export oil & buy wheat from the prairies, if you have enough oil.)
What labels marxist theology applied to its imaginary systems is besides the point. This was all just words which the guys with guns made a certain class of intellectuals spout for their bread, to make sure everyone knew who was the boss.
