Why unions? Good jobs are too hard to come by, and the Republican party is dedicated to asking not why more people don't have good jobs, but why a few people still do even though they're not the corporate executives and Wall Street bankers who Republicans believethe best of everything.The rich are getting more and more of the money, and they're using it to buy more power and more opportunities to get still more money.It's worth thinking about Labor Day, and supporting unions, because unions are a force, however small, against this growing inequality. In that race-to-the-bottom context, union workers do better. They're not making Wall Street money, but they're doing better than Walmart money:Unions help people do better and they promote equality, closing ethnic and racial pay gaps. As unions have declined, income inequality has risen , and that's no coincidence. Union members or not, workers benefit from a strong labor movement. And yes, road or building or bridge, workers built it.
