. . . We have so much more work to do. And everything we fought for during the last election is at stake in this election. The very core of what this country stands for is on the line — the basic promise that no matter what you look like, no matter where you come from, this is a place where you could make it if you try. The notion that we’re all in this together, that we look out for one another — that’s at stake in this election. Don’t take my word for it.

More of our prosperity was built on risky financial deals and homes that we couldn’t afford. And we racked up greater debt, and incomes fell and wages flat-lined. And the cost of everything from college to groceries went through the roof.
