I saw in an earlier post that Randy Wray was interviewed by Thom Hartmann, where the question was posed, "Why has the dollar fallen so much since the 1970's?"
Well, it didn't. Take a look. This is the dollar index against a broad basket of currencies.
The dollar may have gone down against the major currencies, but when viewed against a broad basket of currencies, it didn't go down, it went up.
The statement that the dollar went down after we went off the gold standard is commonly put out there, but it is wrong.
Here's the link to the Fed data for anyone that's interested. Enjoy.
