The problem in the US is a smaller and smaller percentage of the citizens are working and those that aren’t are retired or on welfare. This means that there is a less and less money for goods (why was last Christmas spending less than 2013?) Unemployment is a meaningless value If there were 50,000,000 people in the country working and do one was looking for work the unemployment rate would be zero. But with 320,000,000 people in the country probably 160,000,000 should be working. If the right number of people aren’t working than the government makes up for it by printing money but that doesn’t work in the long run and thing collapse.
