Consider this scenario. A world overburdened by debt that it cant pay back agrees to a form of global bankruptcy. The ones who hold the debt (maybe even you or I, in our pension funds) lose out, and a new financial system is discussed. Perhaps this system is backed by humans as value. Each human who agreed to become part of the system would be given a debit value. Perhaps the debit value would be based on what the individual was promised before....for those of us who had pensions or money in investments, we would be given a debit value of, say, 200,000 units. Folks that were poor before would, of course, have to be given less of a debit value...otherwise the system would be unfair. A poor man in India, for example, may be given a debit value of 100 units. Under the new system, however, he could earn units at the same rate as a man in America could, provided he had the education and skills to justify his earnings. Only those who were tied in to this system could participate, for their pledge would be their work and value. Health care and welfare would be built into the system, though at vastly lowered economic rates and ratios. Caring for a dying poor man, for example, shouldn't be the responsibility of those with more units exclusively...every human in the system would be equally taxed for such care.
Those who refused to pledge their allegiance to this system would be unable to buy, sell, or participate in welfare and health care benefits.
Participation alone would be "the same mark". Either you were in or you were out.
