Is this still a land of economic opportunity?

Americans who endured the brutal 2007-2009 recession and slow recovery now are seeing an economic sunrise: Wages are up, jobs are growing and more families are lifting themselves up out of poverty. And yet, dark clouds are still hanging over millions of Americans. No set of sunny statistics can help an unemployed coal miner in Kentucky pay the mortgage. Upbeat wage data won't reassure a Michigan factory worker who is nervously watching robots replace his co-workers. In this election cycle, candidates are responding to voters' anger and anxiety about an economy that -- yes, has improved dramatically -- but still feels uneven and unfair to many.
