There are serious ethical problems with a capitalist system, especially when it comes to the necessities of life, but there’s also ample evidence that other economic systems in practice have been just as bad of not worse regarding food security, eg follow the history of the USSR from the Holodomor in the 1930s to empty grocery shelves and bread lines in the 1980s

I cannot comment on communism as there has not been a true communism in the world yet, but dictatorships sure have been bad.

No system be it either communism or capitalism can be applied 100%

If we compare today’s capitalism it’s only fair that we compare it to real world application of communism.

As a Pole that was raised in a country freshly out of this system I can only tell you that you would have to be mentally insane to ever consider communism and expect it to work even half as well is it should on paper.
