It's a mystery to me,why can't it just go on as is ad infinitum?

1st world countries ie USA,Japan,Switzerland and Eurozone etc gets to print fiat as fast as the presses can roll all year long and distributes said cash at 0% interest to elites and companies for share buybacks etc and everybody claims profits at year end as markets hit record highs.

Yet if a 3rd world shithole tries the same tactics ie Venezuela,Zimbabwe their economies are destroyed?

Double standards?
