I'm sorry, what kind of anti-capitalist propaganda is that? Suggesting that it is not Pareto efficient,

A simple example is the distribution of a pie among three people. The most equitable distribution would assign one third to each person. However, the assignment of, say, a half section to each of two individuals and none to the third is also Pareto optimal despite not being equitable, because none of the recipients could be made better off without decreasing someone else's share; and there are many other such distribution examples. An example of a Pareto-inefficient distribution of the pie would be allocation of a quarter of the pie to each of the three, with the remainder discarded.

The Elon picture is the critical example from Wikipedia on something that is not Pareto efficient, which capitalist celebrate so much! The socialism example is however Pareto efficient!
