The communitarians may say you've been enjoying too much individual freedom, and that you must give up some of that for the benefit of the community. But they really mean that they want more power over your life - to force you to subsidize, obey and conform to their choices.
When people do things for you, it's because they want to - because you, in some way, give them something meaningful that makes them want to please you, not because anyone owes you anything.
Being a politician means never having to say you're sorry. You don't have to say, 'I never should have voted to subsidize that ridiculous Enron project in India.' ... After all, they're greedy businessmen and you're a selfless public servant.
