Indebting two generations of children yet born.  Momma must be sooooo proud. 

We won't have the water to support all these new people.  Unless we pay to import it with the tolls collected on all these new highways.

That 2050 vision will not manifest. Instead, as gas prices rise to $10 and then, $20 per gallon, you will see a complete standstill in road construction. You will see RVs abandoned, SUVs will become dinosaurs and airports will become graveyards for airplanes.  Before that happens, you won't have enough water for your own citizens let alone vegetation.  Overpopulation will not tolerate further growth in Arizona.  You can bet on it and you can count on it.  You will be forced to come to terms with limits.  I guarantee it as a man who has seen it first hand around the world.   You are so far over carrying capacity today that it will be a miracle if you survive with the population numbers you manifest today.
