Why should Global Obligations work when other utopias fail?
This idea does not depend entirely on altruism. All members are entitled to the benefits, rather like insurance. Global Obligations will earn “commission” on the contributions from the more affluent members which will be added to the capital of the organisation so the investment income can be redistributed to needy members. Global Obligations will also accrue donated or earned capital, and use this investment income as well to cover part of the cost of the contributions from the more needy members. Global Obligations also does not require a majority in any country to begin. It just needs a few (thousand) affluent individuals accross the globe.
