Ever since the financial crash of 2008, we've been having an anxious national debate about the growing income gap. What does it mean for American society when most workers' wages are flat and almost all economic gains flow to the top 1 percent — or to the top one-tenth of 1 percent?
But it's a discussion that too often turns into a sterile squabble over economic theology between liberal populists, who want to tax the rich, and supply-siders, who say that cutting taxes will add jobs, reward entrepreneurship and raise all boats.
So maybe it would be helpful to set the problem of the income gap aside for a while and focus instead on a problem everyone can agree on: the opportunity gap.
The American dream is the idea that anyone can get ahead in life with talent and hard work. But that ideal of wide-open opportunity has been dented quite a bit in the economic stagnation of the last few years.
And that's a problem that Republicans as well as Democrats recognize.
"What I believe unites the people of this nation . is the simple, profound belief in opportunity for all — the notion that if you work hard and take responsibility, you can get ahead," President Barack Obama said in his State of the Union address this year.
"Let's face it: that belief has suffered some serious blows."
"The income gap gets the headlines," said Sen. Rob Portman, R-Ohio, in a speech last week. "But it's the opportunity gap that should concern us all." In recent months, Rep. Paul D. Ryan, R-Wis., Sen. Marco Rubio, R-Fla., and other potential GOP presidential candidates have made a point of calling for a new conservative agenda to help the poor and the struggling middle class. Their ideas all build around the emollient idea of increasing opportunity for everyone.
"If we focus on the question of opportunity, the two political parties may actually be able to have a respectful, fact-based discussion, even though they obviously won't agree on every solution," said William A. Galston, a former Clinton aide now at the Brookings Institution.
If only it were that easy.
