If the dollar becomes almost worthless so that you need a wheelbarrow full to buy a loaf of bread the person?

that purchased a bunch of land at fixed interest rate loans just before the dollar collapsed would be sittin' pretty. You mortgage to buy some land at say 300,000 dollars with a fixed interest rate. Then the dollar collapses so that same land to purchase would be 500 trillion dollars. But you already bought it so your price doesnt go up. Your fixed interest rate doesn't go up. But wages go up say minumum wage becomes 12,000 dollars an hour. So you can pay off your loan with inflated dollars. So when should a person start running up massive fixed interest debt, because if you do it too soon before the dollar collapses your pretty much in trouble. So that is the question: when?
