Two Problems for Would-Be Communists

Under communism, the slogan is "From each according to his abilities, to each according to his needs." There are two problems if you are going to go that way. The first is, how are you going to get people to work without the profit motive. You are going to get what you need regardless of whether you work hard, or goldbrick. The second problem has to do with how you decide who needs what. In communist countries, the Communist Party (the vanguard of the Proletariat), decided what people needed, and, unsurprisingly, they decided the Communist Party needed more than non-Party members.
