I understand the macroeconomic argument, but I still think that the fact that inflation will totally destroy an uninvested, normal middle-class-sized savings account in less than a generation is a huge obstacle for normal people building wealth. That is the inherently bad thing about it.

I primarily attribute the growing "wealth gap"---the growth in the net wealth owned by the top 0.1% of people, from a 5% share in 1970 to a 20% share in 2020---to the end of Bretton-Woods and the gold standard (1971).
