Housing debt is mainly held by the wealthier half of society. Credit card interest rates, as well as other unsecured consumer lines of credit, are so incredibly high that inflation is far from reducing the value of those debts, it merely slightly slows their rate of growth. If you think inflation's impact on debt favours the poor, you have to look at the interest rates available for borrowing. Poor people get loans without collateral, so their interest rates price in inflation and then some. Wealthy people get collateralized loans at interest rates below inflation -- for an extreme example, look at how billionaires borrow against their stock holdings rather than sell stocks for cash.
