Only insofar as one is willing to subsume multiple economic systems without even marginal ideological similarities between them as a single system that bears the guilt for the actions of the polity.

I wouldn’t say central planning has caused most deaths attributed to ML countries, and I wouldn’t say capitalism has caused most deaths attributed to non-ML countries. Both have caused more deaths than they have any right to, but the fundamental problem lays in political and military power more than the exact structure of economic hierarchies. They can feed each other, but then we must get into questions of how much guilt and in what proportion - especially since ideological application in the real world is rarely ‘pure’ - each piece holds.

Not only that, but these two economic systems have dominated an age where an order of magnitude more people live on the planet than previously. It may be technically true, for example, to say that capitalism or central planning has killed more people than feudal economic systems, but that does not really capture the actual moral value of each of the three.

Capitalism is shit. We need to get rid of it. But that’s not the same as saying it’s responsible for more suffering and death than any other.
