And by money I will assume you are referring to government issued fiat debt noted. There is always enough of them to do basically anything a government wants.
When you understand how "money" as you call it is created you will have better knolage to see what is happening.

There a painful difference between education and knowledge.
Those with education historically suffer while those with knowledge navigate the future with certainty.
