Correct me if I'm wrong, but shouldn't we be looking at whether the people at the bottom gained more wealth, rather than what percentage of the gains they hold?

Correct me if I'm wrong, but shouldn't we be looking at whether the people at the bottom gained more wealth, rather than what percentage of the gains they hold? The wealthy will always have more opportunities bc of the 80/20 rule, and the fact that inequality is inherent in all animals. It is called "trickle down" after all, not "ration down."
