"The only way to keep the economy going over the long run is to increase the wages of the bottom two-thirds of Americans. "
No, I totally disagree. Whilst I don't actually AGREE with TB, either, there's half a point in what he says.
My view is that the only way to keep the economy going, over the long run, is to balance the income and the productivity of said 2/3 of Americans (and people in the rest of the world, too). If you don't CONTRIBUTE to society and the economy, you aren't entitled to TAKE from it, beyond mere subsistence.
There are many ways to pervert that simple equation. Some we call socialism, some "the free market". None are ideal, imho, but some are closer than others...
