This covers many words used for money, although there are many more used less often. The exact history of "bucks" used for "money" is uncertain, but the leading theory, which seems likely, is that "bucks" came about as a substitute for money in the 1700s, when deerskins were a common medium of exchange for other items of value.
We hardly see half-dollars now, and although quarters are still quite common, we seldom hear them referred as "two bits." In fact, from an informal survey I took, most people about forty years and younger do not have any idea what "two bits" or "four bits" or "six bits" or any number of bits refer to.
Property's worst enemy is theft: theft makes property insecure. And unless property is secure, it can't be accumulated and it is wasted. The increasing incidence of heists on grain, Argentina's most valuable export, indicates that property rights are becoming more insecure and that the economy only has one way to go: down the tubes.
