I'm a bit annoyed at the prevalence of the socialist and communist ideology in the public mind when it come to directed economy.
Both have been written in the 1800's and fail obviously to take into account recent phenomenon (digital economy, drastic improvement of production power,...).
When you speak about socialist policies in northern Europe, you are pretty far from the Marxist theory, and the most relevant similarity is care for the less wealthy. But that is a quite common concern, and Sharia, for instance already put a tax for the rich to help the poor.
Now on the matter of "don't you dare to spend my money for me", that "money" is not the direct product of your labor, and the economical system is not a god-given perfect meritocracy.
Law of offer and demand hardly make everything fair, and you may indeed have to correct some inequalities that may arise.
The most easy example is Nikov's minimum wage : working in a capitalist system naturally lead to a compression of the workforce's salary. You have to put a stop at it if you don't want to have a significant part of your population living in misery.
There is different reason for that : being a decent human being is one, but no the only one. Very poor poeple are more likely to commit crime, and that is costly, are less educated, and therefore cripple democracy, as showed in the US by the teaparty (kudo for having a candidate to the presidency in a tele-reality emission, your politic have now sunk to a new low).
The last argument is actually freedom and the right to quest for happiness : you are not free when you are dirt poor.
