Very interesting. The reset(like what happened in Mexico) is designed to steal from people and keep inflation going. They cut off three zeros so 1,000 pesos went to 1.
This tricks people psychotically because if price of an item goes up 1000 to 2000, that's a lot, but if it only goes from 1 to 2 it makes it seem like prices are increasing slower. It also fools people due to the smaller number. People will think, "Oh it used to be 50 but now I'm only paying 2" even though it still rose the same.
