The founder of Wikileaks, Julian Assange, in an interview with BBC while out on bail pending possible extradition to Sweden concerning sexual assault without a condom charges, had this to say concerning his persumably unrelated mission with Wikileaks:

"Every person who has some ability to do something about it, if they are a person of good character, has the duty to try and fix the problems in the environment in which they're in."

This is, of course, is equivalent to the first half of the 1875 Marxist slogan:

"From each according to his ability, to each according to his needs."

Marx's version is to be preferred because Assange allows that persons of less than "good character" are relieved from said duty.

The whole idea is somewhat mystifyihg, and in some conflict with the American idea of a right to pursue happiness.

The trouble is that there are always and always will problems.  To say individuals have an actual duty to solve problems not of their making hands Society a sweeping, blunt, oppressive and easily corrupted tooland liable to wax repressive.  Further, said duty is bound to conflict with the individual's pursuit of their own self interests, their own happiness.

A big part of the genious of the American Experiment is the attempt to construct a society in which people's individual self interests are cultivated in ways intended to benefit Society as a whole.

This Assange/Marx idea fails to acknowledge that the human animal is motivated first and foremost by their own self interest.
