If America's economy keeps going the way it is, will we end up like a dried, slavery wasteland like Zimbawea?

Zimbawea kept printing money and hit hyperinflation, which made everyone poor, cause riots, dicatation, and caused slavery and kids without parents having to fight for survival.......my history teacher says America is headed in this direction within the next decade, Pat Robertson says two years, my grandma whose older than both of them and has lived through almost every abd thing in America in the last century, said they're jokes, and no matter how bad it gets, because we have resources and a constitution, America cannot become that bad.....but I'm sitll scared, what do u think???
