If every dollar must be backed by a certain amount of gold, then you cannot create money out of thin air. The gold standard says you must have the gold first. Governments find it harder to wage war, dole out entitlements and build public works with a gold standard tying them down. Banks can’t lend as much money; hence they can’t make as much money. This is why the banking interests of this country backed the creation of the Federal Reserve. They appreciated the value of a good cartel.
