The Slaughterhouse Cases, resolved by the U.S. Supreme Court in 1873, ruled that a citizen's "privileges and immunities," as protected by the Constitution's Fourteenth Amendment against the states, were limited to those spelled out in the Constitution and did not include many rights given by the individual states.

the fixed value of gold make the large business able to stack up their gold without   being worried that it would devaluated.

- william jennings supported the silver standard while mckinley supported the gold standard

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.
