Why make more lanes and then have the same amount of people to run them? If they started charging people to cross it would either cut down on the crossers and/or make them more money. What business couldn’t use more money? If they can staff up without charging then I’m all for it. Seems to me with proper planning 2 hour waits at the border can become a thing of the past. They never ever have all the lanes open as far as I know.
