My grandmother's house still has asbestos in it ($400k house in New York). Short of tearing her house down and building a new one there's no way to fix that, but decades later I'm benefitting from the ban by living in an asbestos-free house built after the ban. Gotta start somewhere even if the benefit isn't felt by everyone at the same exact point in time. It would definitely benefit the rich first since they tend to be the ones building new property.
