Everyone gets paid equal. Lets say there is a Sheep, who is the head of all COWS. This Sheep controls all production made by cows. For every bottle of milk each cow produces, they get a fair share of land/grass. Every cow is treated equally. Even, if one cow produces MORE milk than the other, they will still receive the same share, as to the cow who produced LESS milk.
Or think about a farmer. A farmer who sells his/her cows will get the same as, let say the firms/business who BUYS the cows from them and then further sells them to the global/domestic market.
I really hope this makes sense...Communism is a political and economic goal, that the government uses to try achieving equality. A lawyer, who spent years studying at a tertiary level, will receive the same pay, as that to a teacher. The Government takes all the income, and distributed it evenly. This type of government, is unrealistic and doesn't work. This was what started the Vietnam War. USA, NZ and Australia against, the communist Vietnamese. Although, the purpose was for a good cause, it doesn't work! The government tends to be eager to take advantage of the money, thus becoming easily corrupt. The people become unhappy, because many feel they deserve more money, dependent on their job stakes.
I hope you followed through. Chur! :)
