It's a big issue for everyone, or at least should be. You really should try it sometime. You might find you like it.
The problem there is, I don't think Shaman wants to think. Most liberals do not, since it will automatically challenge their views. I used to be one, and thinking through the topics is exactly why I became a conservative.
That used to hold some importance to me. But when I started looking at some of the Nobel winners, they make a mockery of the Nobel Prize.
For example Kofi Annan was given an award, but was involved with the Oil-For-Food scandal. In fact a key player who met with French companies, which lobbied him, and won the bid.
Yasser Arafat, a well known terrorist, who openly stated on Arabic radio his intentions to wipe Israel off the planet, and slaughter every Jew in Palestine. But since he spoke of peace on the English radio, he was given an award.
Rigoberta Menchú Tum, who wrote a book about her life in Guatemala, and was given an award. Then 10 years later, a massive investigation into the book, revealed entire sections were fabricated.
And of course, are all time favorite... Jimmy Carter was given the Nobel prize, even though he successfully didn't defend a US ally in Iran, didn't stop an anti-US force from taking over, successfully didn't save US citizens at the embassy in Iran, successfully did give the anti-US forces bran new US military hardware in a failed rescue mission, successfully created an energy crisis, and successfully got double digit inflation and the highest unemployment rate in 30 years.
And what did dear ol Jimmy do after this? He built houses for Habitat for Humanity. Great so all those thousands of other volunteers should get the Nobel too?
Bottom line is this... just getting the Nobel Prize, does not automatically mean anything. Krugman might have gotten the prize, but so did a well known terrorist. I have already posted articles by economists on Krugman, and even they say he often is partisan in his thinking.
