If I was in Mexico and the cartels were
killing everyone in sight and my kids were starving. I wouldn't find it
"cruel" to move them to a place where they had a fighting chance for a better life.
This theory that comes from
"do whatever it takes to get rich" of capatalists, that the poverty stricken won't do whatever it takes to survive.
I've been to Mexico,

Baviacora to be exact where I was mining gold in a placer mine with my Dad and hired Mexicans. (long story.)
Anyway I left a few months later, no gold and it was about 115 degrees everyday. My dad stayed behind to sell off the equipment and tie up all the lose ends. I got a call about a month later while I was on a patio at my local pub in that lovely half drunk bliss where everything just feals great.
He had been stopped by some militario's on the road leading from the mine going into what some might call "town." The men and children with machine guns that had stopped him looked the part, full camo and all. But then he noticed they were wearing tennis shoes and that was not the official combat boots most of the corrupt swine wear. (their were rumors in town that he was taking pounds of gold out of the mountain, think in total we pulled out a half once.) He told them he had his ID in his truck and the second he got in he peeled out and took off down the road.
The Mexicans chased him and opened fire, hitting his truck several times. My Dad (Who always leaned a bit to the left) told me his only wish in the world was to have a gun at that point so he could return fire.
This road was intense, I remember it still. Bavicora is in the Sonora desert and this road goes up through the hills and winds around dangerously tight corners with about a 100 foot drop in some spots. Eventually the Mexicans tried to squeeze up next to his truck and it didn't work out so well for them and they went off the side.
My Dad did not stop. He said he even gunned it through the next checkpoint at about 90. He kept on going till he was in Texas, where he called me from a hotel room (he was very shooken up and I think it still affects him to this day.)
This is everday thing in Mexico. Violence and cruelty. The people are
beyond poor and the government is run by drug dealers.
If I was born there, I would make it my lifes goal to get out, to get to the US and have a fighting chance.
