"I think they're sending a message that reflects the opinion of the people that elected them," said Gerald P. O'Driscoll Jr., a former vice president of the Federal Reserve Bank in Dallas and a senior fellow at the Cato Institute. "By doing it at the state level, it's kind of trying to push, force the federal government to pay attention to this. Let's call it a symbolic act of sending a message."...Peter Morici is quoted as saying that the gold standard will come unless the U.S. government gets its fiscal and monetary house in order. Gold is more trustworthy than, say, the renminbi.
"There's a growing realization that the system does not work. The rest of the world is increasingly angry, upset at that policy because it has huge effects in other countries, mostly in the developing world," O'Driscoll said. "Both domestically and internationally, there's a sense there is a need for a new monetary system, but I don't think there has been any consensus or coalescing on a particular idea, including gold."
