When will the monetary system collapse?

the economy's of so many countries will go down and even if they print more money(out of nothing by the way, not by gold) there will be more debt because in reality money is debt, because the only way the public gets money is through loans from the federal reserve. and whats more is that we will never be able to pay off the debt because even if every single amount of money goes back to the banks there will be more money owed due to the fact that there is interest. if you look at graphs, the same countries with the highest gdps also have the highest amount of debt.
