A couple of articles in these parts have looked favorably on an increase in the gas tax. I think it would be a mistake.
States should handle a much larger share of transportation funding than they do. The federal government should cut gas taxes to a level commensurate with its legitimate responsibilities in this area, and states can then levy their own to finance the improvements they need.
I also think that the entire push for a big federal infrastructure push is misbegotten, and it is therefore foolish to get into a detailed debate about how to finance it.
