When will Carter and Greenspan just shutup?

I don't know what it is with former famous political leaders, but they seem to be having a problem keeping their mouths closed. Just a few days ago, former President Jimmy Carter went off as saying "the current administration is the worst in history". Later, Carter claimed he was only referring to the Bush Administration's foreign policy.

But, like Greenspan, what good did these comments really do for the country? Confidence is already near all-time lows, set when guess who was President-Carter himself. A vast majority of Americans in both parties know how poorly Bush has done in respect to foreign policy, so why does the former maligned leader feel the need to state the obvious? Considering his track record, Carter has no room to criticize or talk.

Today, former FED Chairman Greenspan decided to tell the world that China will have a big sell-off at some point. Well, no kidding! Anyone who follows economics and investing understands that China is due for a correction at some point. Did Greenspan really find it necessary to state the obvious as well?

However, I fail to see where this "big" correction will come from. If you take into account the P/E ratios over the projected five-year earnings growth rates in China, the stocks seem more appealing then those in the United States. Yet, Greenspan seems to ignore key numbers such as this all too often. To be critical of China, when you have been linked directly to many of the problems the US Economy currently faces, takes one arrogant and senile former economist and politician.

Carter and Greenspan need to go play a round of 18 and accept the fact that they failed during their tenures.
