Yesterday, in a supermarket, the woman ahead of me in the line had a minutes-long (one-sided) discussion with the cashier about the fact that she doesn't like "multi-millionaires" because there are so many poor people and multi-millionaires have so much money they don't need.
I didn't say anything (the cashier was annoyed enough), but I was thinking. Let's assume she was right and people who have money they don't need should give it away. Let's forget games like "who determines what is needed" because there are enough people who would volunteer to make that decision and not all of them would be unreasonable about it.
But even assuming all these things, the question remains why we should pick on "multi-millionaires" (i.e. people with money) when money is not the only measure of whether somebody has more than he needs.
Money is simply a measure of wealth and wealth is created by spending time at a certain ability level. Ignoring ability (which would obviously result in an uneven "distribution" of wealth created, namely a _non-distribution_ where wealth stays where it was created) it comes down to how much time each individual decides to convert to money. Time itself is wealth too.
Now, if an individual with more money than he needs should give up that excess money, I figure that an individual with more time than he needs (perhaps the individual doesn't have a job) should also give it up. Personally, I value my time higher than my income which is why I sleep, play and study longer hours than I work.
Luckily we already know how much time an individual needs, as per the wisdom of European socialism: 131 hours/week. This is the full week's 168 hours minus the 37 hours of work a week.
This means that society can demand that the unemployed spend 37 hours of their time working for charity (or the state).
Oddly enough, this is not meant when left-wingers speak of "from each according to his ability". In fact today's socialism focuses mainly on the better-known second part of Marx's witty statement: "to each according to his needs".
