Stimulate with all that consumer spending by sending the illegals back . . . pronto.
1. The Bus Industry, Greyhound, Trailways and the like. It would be a big boon to be picking up passengers from the upper 57 states, and bringing them South... WAY South, no need to just stop in Mexico.
2. Luggage Industry needs a big pickup: luggage of all sizes, duffle bag industry, shipping trunk industry, backpack industry. These folks have accumulated ALOT of stuff over the years.
3. Map Industry. No need to waste ink in printing up maps, though. Ink can be saved by not printing East-West roads. Only print half of each North-South line... just the South-bound side need appear.
