The book written by "Lawrence Lepard" discusses in detail the effects of printing money. When a country's central bank prints excess money, the effect is to cause inflation. Hyperinflation occurs when a country prints too much currency, as happened in Zimbabwe in 2000 and is currently facing an extreme situation in Venezuela.
And US inflation rose 2.4% as reported by @WatcherGuru. Even from the same source, if the debt problem is not resolved, then get ready for a major crisis to be triggered.
We are increasingly aware that the value of money is decreasing day by day. In an effort to save value, choose assets that have the best hedge.
