We do have way too much debt---and when we have too much debt, the inevitable result is inflation. Thank you, President Trump, for adding $8.4 trillion to the national debt and for financing the deficit by printing money.
But that doesn't mean that debt is intrinsically bad, or must always benefit the rich at the expense of the poor. Like any other tool, it depends on how you use it.
Society doesn’t need to operate with so much debt. Usury is a financial tool that benefits the rich.
