People shouldn't cross illegally, but they shouldn't deserve to die either. That kinda reminds me of the people from East Germany trying to reach West Berlin.
I'm not comparing Mexico (nor any other country in South America) with East Germany, but the situation is comparable in that these people are trying to reach a better life. Whether they can do it at home or not, is debatable.
The difference is, we can't afford to have them all come in, as they wish.
Mexico is providing reasons & assistance to get yours out of their homeland & into ours.
East Germany (et al) was keeping them in.
