From a recent Bloomberg article: Wealth of bottom 50% doubled between 2020-2022. Top 1% rose significantly. While the remaining 49% didnt budge much. Interpret it for your supply chain concerns.
The bottom 50% own very little. Home ownership rates in the USA are like 65% and poorer people are less likely to own their homes.
So the answer is likely, a negligible amount. The increase in wealth among poorer people was most likely driven by stimulus money and a bit due to wage increases (which also favored the poor).
