High inflation discourages high debt.

High inflation effectively front loaded loans that had fixed repayments (such as mortgage repayments) and the high interest rates that went with them (they move togeter - its called the Fisher Effect - https://moneyterms.co.uk/fisher-effect/ ) meant lenders were willing to lend a much lower multiple or income.

In most places (and definitely in the UK) house prices were much lower relative to incomes when we had 10% annual inflation.
