What is the philosophical argument that explains in principle why owning significant amounts of wealth when others are in poverty is considered unjust?

Question

I’m not looking for the obvious moral explanation, but the philosophical basis behind that line of thinking. Thanks!

Answer 1

It could be that one cannot find a philosophical basis for what is rooted in morality. Your question may mistakenly presuppose this. A moral principle, or in your words “the obvious moral explanation”, whatever it is, may be more philosophical than you are allowing. A related question might be why the need for philosophical arguments or principles for that which is so easily explained in moral or even sociological terms?
