Seems Forbes disagrees with you folks who take a partisan economist's word for it. And yes, income inequality is bad. Bad for a consumer driven economy. It's that simple. It's crazy that people fail to see it. No actually it's unbelievable.

And an opinion piece in Forbes is not that of a partisan economist?

The article you cite assumes a causal relationship, although it is not proven. And the problem seems to come from gov't interference, according to that same article.
Dismissed.
So you saying Forbes is liberal?
I would care to guess that 99% of all economist know there is income inequality. I could post article after article from economists of all stripes acknowledging that there is in fact income inequality. Sowell is the right wing's version of Krugman. They are both political hacks.
And we all know what you are about Rabbi.

Forbes, the Wall Street Journal, The Economist, I even included a pretty hard far right resources (Townhall), they all realize the yes, there is income inequality. It's a danger to the US economy.
I love how our resident non-economists know so much more about economics than the world's top economists of all stripes. We are so lucky to have economic geniuses here at USMB!
