The best policy measures are those that solve two or more problems at once. So consider this idea: Let's tackle Washington's revenue challenges through tax hikes that mainly hit suburbanites and incentivize urban living.
The need for more revenues is clear enough: federal taxes are near a 60-year low even as the Baby Boomers retire, China rises, infrastructure crumbles, and deficits stretch as far as the eye can see. Enough said on this point.
