I've heard this somewhere before...

This sounds a lot like what I've been writing lately.

As a matter of fact, not only does he come to the same conclusions...

First, growing inequality is the flip side of something else: shrinking opportunity. Whenever we diminish equality of opportunity, it means that we are not using some of our most valuable assets—our people—in the most productive way possible. Second, many of the distortions that lead to inequality—such as those associated with monopoly power and preferential tax treatment for special interests—undermine the efficiency of the economy.

He even finishes off where I have on past occasions:

Alexis de Tocqueville once described what he saw as a chief part of the peculiar genius of American society—something he called “self-interest properly understood.” The last two words were the key. Everyone possesses self-interest in a narrow sense: I want what’s good for me right now! Self-interest “properly understood” is different. It means appreciating that paying attention to everyone else’s self-interest—in other words, the common welfare—is in fact a precondition for one’s own ultimate well-being. Tocqueville was not suggesting that there was anything noble or idealistic about this outlook—in fact, he was suggesting the opposite. It was a mark of American pragmatism. Those canny Americans understood a basic fact: looking out for the other guy isn’t just good for the soul—it’s good for business. [emphasis mine]

Do yourself a favour and pass the article around. It's sobering, it's correct, and it's important. We need to reclaim the power of the middle class.
