Capitalism sucks you say. Allight. But who’s going to make the screws in your utopia? No, seriously, who is going to spend their days making screws or lightbulbs or the plastic covers for electrical outlets? Because if you don’t have a good answer to that question, it's impossible to take your ideas for a new society very seriously.
"From each according to his ability, to each according to his needs." Surely, comrade, you have the ability to make a screw. Or are your abilities simply too important for screw making? When one hierarchy falls another always grows to take its place.
You don’t judge a complex system like capitalism or socialism based on what it would be like if was perfect; because it never will be. You judge it based on what it will be like when it gets hijacked by sociopaths and criminals; because if it can be, it absolutely will be.
