A discussion about global economic inequalities.

The world GNP keeps rising with the world population.   This is as it should be.  However, the distribution of this wealth is also transforming, so that a minority are becoming very rich indeed, while both the numbers and the proportion living in relative (some say absolute) poverty keep increasing.  These problems are typically left to governments, NGOs and religious institutions to deal with.  Does any further obligation devolve to ordinary lives?  

I  propose that self-interest and 'altruism', utilitarianism and a priori ethics, at least in this case, are indistinguishable.

Is economic inequity a moral issue?
