> That's not how a reserve currency works. You borrow to fund growth and let inflation take care of the debt.

Inflation might take care of the debt, but it is terrible for currency holders.

that's why you get interest and above a certain amount of savings, you invest in the market to get growth. otherwise you buy land or gold.

This is a strategy to protect against currency devaluation, but you still need to worry about interest rate risk (as do companies in the public markets, so investing in stocks isn't a sure thing).

Unfortunately, for people who live paycheck-to-paycheck, there's not much to be done besides wait for wages to catch up. And in general, wages don't keep immediate pace with inflation. The net result is that lower-income workers suffer the bulk of the consequences of high inflation.
