This is somewhat of a long read but very interesting. This author is pretty harsh on Obama but some things he says I agree with. I think Obama had the chance to do more in his first term, however I do feel that in several instances he had to fight the Republicans tooth and nail to get anything done. We cannot ignore that fact. This author does a great job going back in time to explain what happened to the Democratic party.

The first piece of evidence is what’s happened since the financial crisis. This is the great story of our time. Inequality has actually gotten worse since then, which is a remarkable thing. This is under a Democratic president who we were assured (or warned) was the most liberal or radical president we would ever see. Yet inequality has gotten worse, and the gains since the financial crisis, since the recovery began, have gone entirely to the top 10 percent of the income distribution.

This is not only because of those evil Republicans, but because Obama played it the way he wanted to. Even when he had a majority in both houses of Congress and could choose whoever he wanted to be in his administration, he consistently made policies that favored the top 10 percent over everybody else. He helped out Wall Street in an enormous way when they were entirely at his mercy.

He could have done anything he wanted with them, in the way that Franklin Roosevelt did in the ‘30s. But he chose not to.
Money in politics is a big part of the story, but social class goes deeper than that. The Democrats have basically made their commitment [to white-collar professionals] already before money and politics became such a big deal. It worked out well for them because of money in politics. So when they chose essentially the top 10 percent of the income distribution as their most important constituents, that is the story of money.
