you cannot understand the socialist idea, because you lack the basic knowledge of what communism, socialism and capitalism is. If you would have studied economics, like I have, you would know that communism isnt socialism, and you would know that the opposite of centrally planned economy is free market, but socialism doesnt necessarily mean that it has to be organised in a system of a centrally planned economy.
If you knew about society, you would know that people arent poor because they sell drugs, commit criminals acts, and are uneducated and unemployed, BUT
they are uneducated, unemployed, commit crime and sell durgs BECAUSE they are poor.
A society which doesnt guarantee free and accessible education for everyone and guarantee a job after school is doomed to be dragged into crime and internal struggle of its society.
Capitalism is a system that punishes the unlucky and most hard working people, and rewards lucky people born into rich families, with relations at the top of the society, and greedy people who exploit others for profit.
