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.
In his State of the Union Address last week, President Obama announced a renewed commitment to manufacturing in the United States. While the commitment to rebuilding the country's manufacturing base is welcome, he unfortunately left the most important item on the list off the agenda. President Obama failed to commit himself to restoring the competitiveness of dollar as part of his agenda for bringing back manufacturing jobs. The value of the dollar really has to be front and central in any effort to restore U.S. competitiveness since it is by far the most important factor determining the relative cost of U.S. goods compared with goods produced elsewhere.
