Six long years into presidency, Barack Obama has finally made the middle-class an explicit priority— placing “middle-class economics,” as he called it repeatedly in Tuesday’s State of the Union address, front and center on his agenda. But what the president is asking for may be too little and it’s arriving far too late. While his proposals are sensible— lowering the tax burden on middle-class families and expanding access to education, job training and retirement, in part by closing loopholes and raising taxes on capital gains—very few of them have much chance of passing.
