The truth of the matter is that they wont stop. Government is in perpetuity which and the Central Banks are the ones behind it for government to still function, one key element that must stand is the economy. Even after it has failed several times, there is no alternatives on the contrary. Today, United States owed larger percentage of the total world debt but the government is still borrowing, dollars is still available to support all of the government activities and even by borrowing more.

The moment governments stop giving support to fiat, everything would have gone haywire, the price of goods and services would have shown their true state which might be unattainable and the real pump and dump would have been witnessed from that end. The politicians on the otherhand have to protect themselves for the next election so they have to keep the status quo.
