“Wealth gap” is a truly evil concept.
What it means is that, if you save your money, or invest it in stuff that holds its value, and create legacy for your children, that is UNFAIR to folks who squandered all they had on tennis shoes, iPhones, and lottery tickets.
YEs, but if you have zero incentive for savers who just see their money eaten away by inflation greater than interest if they try to save, why should they not spend on current needs/wants rather than getting eaten up?
