Dawg, I dont know man…. To each according to their needs is kinda hard to subscribe to before the definition of a post-scarcity society, considering we all have the same needs generally speaking. To use Stalinist USSR as an example work was assigned according to ability, and in some cases who you were or who you knew. Someone had to work the party lines and admin to assign this stuff based on “something”

Edit: i know this example isnt real communism
