Back in the 1970s the US Businesses were doing very good. The workers could afford an 18% mtg on a $40,000 home. But they are less wealthy these days and can’t afford even 7% on a $550,000 home. So the Fed Reserve really can’t raise rates without creating a bigger mess.
And lets not forget the 50 year trade imbalance, buying more than we sold. And globalization, giving away 90% of our auto manufacturing. Plus everything else. And all the Americans, caring only about themselves, or having no choice, buying all the imports, exporting our money to foreign nations.
