  Unfortunately, each and every one of us might have a positive incentive to try to free ride on the efforts of others. My contribution—say, an hour’s work or a hundred dollars—might add substantially to the overall provision. But my personal share of the increase from my own contribution alone might be vanishingly small. In any case of interest, it is true that my benefit from having all of us, including myself, contribute is far greater than the status quo benefit of having no one contribute. Still, my benefit from my own contribution may be negligible. Therefore I and possibly every one of us have incentive not to contribute and to free ride on the contributions of others. If we all attempt to free ride, however, there is no provision and no ‘ride.’
