That city will never be the same. As bad as it might seem, a lot of those that left might be better off.
Well, maybe so, if their new home cities don't collapse under the strain of the influx. I am not optimistic for Houston as one case of sudden stress on the infrastucture. Hope the residents of Houston are prepared for shortages of a number of things.
Houston can handle it, as big as the city is if they just ran off the illegals there would be too many jobs. The thing about Houston, is that it is so spread out. If the actual population of the outlying suburbs were put into the population count, it would be the biggest city in the U.S. Besides, we can always build more jails....
