I'm not Christian, don't believe in the ideas, and have a lot of trouble with the way the religion conducts itself, but I do, however, find a lot of wisdom and practical knowledge in the teachings of Christ, especially concerning dealing with neighbors. Many people here say the problems with Mexico are insurmountable, that they are far too complicated to deal with. I completely disagree. I think people are making the solutions far more difficult than they have to be. It is a human problem, after all. It doesn't take much to put down your gun, step across the border, offer your hand, and try to talk, to make a serious effort to establish a rapport. The problem is that people want to see adversity even when there is none. Mexicans are suffering. Badly. The violence and crime come from somewhere. It doesn't just spontaneously sprout. Drug lords arise in poverty stricken places, and not affluent places, for a very good reason. Poor countries have lots of corruption for a reason (and vice versa, corruption engenders poverty).
I think if you let yourself think about all the tiny problems that can arise then you end up not being able to move at all. But some first step has to be taken. Obviously most of you here are deeply dissatisfied with the present situation. So then, think outside the box, bust the conceptual block. Come up with unconventional ideas and brainstorm. Together. Find solutions, Together. Talk. Together. Stop being afraid of trying something new.
Take the border down. Yes. WIll there be problems? Oh yes. The pressure has been so blocked up that it's going to burst out. But expect that and plan for it. And keep to the idea of forging a trust. Eventually things will pipe down and a balance will establish itself. I don't think the border problem can be solved without some initial steam blowing off.
Change is always preceded by vision that may not be apparent to everyone at first. And it can seem quite threatening and scary.
