I think the general response is, in a real world it's never an all or nothing proposition, and even if it were, the fewer people contributing, the greater the opportunities for those who do. (greater uncontested target market share, less competition, more demand, less supply.) The economics 101 supply demand curve hopefully helps incentivize ENOUGH people at sufficient levels to do what productive work needs/is desired to be done. And if then everyone STILL decides to do nothing, I think we have bigger problems than a matter of economic policy :)
