Why? Do you own the hospital? If you were the gatekeeper would you let him die on the steps of the hospital? What if you knew that it was your new home he was building?
If you hate Mexicans so much why don't you start a movement to stop all new home construction in your town? Put all carpenters, bricklayers, drywall workers, electricians, wholesalers, concrete companies, Realtors, builders, convenience stores, roofers etc out of business. Then who are you going to sell insurance to?
