I know how he can fix the employment thing and slash air pollution in one stroke, plus throw a bone to the "reduce our dependence on foreign oil" crowd as well as doing something about all those obese people Michelle's always going on about: Replace all private automobiles with sedan chairs.
Seriously, think how many people could instantly find employment carrying other people around. As a sop to the #OCCUPY_MOM'S_BASEMENT class warfare crew, you could even mandate that everybody has to do one month of sedan chair duty for the less fortunate every year. Run a commercial showing a couple CEOs lugging a single mom to pick her kids up from day care and those votes are in the bag.
It would cut down on traffic congestion, and it would encourage everybody to move out of those icky McMansion-riddled suburbs and back into arugula- and culture-filled cities where they can be more easily found by their local ward heeler. Plus, it'd be a finger in the eye of those sanctimonious greener-than-thou Europeans at the next UN eco summit in Monaco or Tahiti or wherever they're holding the next one. Exceptions, of course, would have to be made for government employees on important official business, like firemen and policemen and congressmen. Oh, and foreign diplomats.
This is so right in the wheelhouse of some members of the current administration that I'd be kind of surprised to find that a rough draft wasn't already in existence on the back of an envelope on the bottom of a drawer in the West Wing.
