Here is an article by the usually silly David Brooks, on the redefinition of our morality vis a vis materialism. He argues, citing others, that we in the US will have to rethink our attitudes toward wealth and excess in the coming years.

I find it odd that these two cheerleaders of consumerist globalization are now criticizing the side effects of the type of suburban, gluttonous lifestyle that they have spent decades promoting. But if this marks a genuine change of heart on their part, I guess it's welcome.

It's a shame that such common-sense ideas seem new and odd after decades of voodoo experimental economic thinking.
