Or they don't want to live or work in a country that will treat them as a lower class of people. The Mexican people do not like Central Americans for the most part. Plus the US offers high wages and isn't engulfed in cartel wars like Mexico is. If you were fleeing gang violence would you want to settle in a country that has the same problems almost as bad as your home country, or would you seek asylum in a different country that didn't have problems like that?
It takes something specific to create what might as well be termed a "golden horde." This isn't a matter of "dude got tired of the danger one day and a couple other people thought it was a good idea to leave too and suddenly 'we got us a convoy'".
I appreciate your approach but it's a grossly oversimplified explanation for what's happening.
For what it's worth, I've always been a proponent of closed borders except for a few vacationers and immigration through an education track with trade restricted to raw goods. I've held that view all my life and your not likely to change my mind on it though I'm willing to listen and consider. I'll also quickly admit that it is going to seriously bias my view and discussion with you.
Honestly I was against open borders until I worked with some illegals and my daily interactions with them changed my views. I felt it was very hypocritical of me to be saying "kick them all out" when I was spending 12+ hours with them some days. In my interactions, I saw some of the animosity that occurs between Mexicans and Central Americans. Most landscapers in Atlanta will tell you to be careful mixing the two groups and if you do, then make sure the crew leader can keep the peace. Some landscapers will only hire workers from one country in order to avoid any conflicts.
Honestly I think this convoy is either a group of "coyotes" who are being brazen or the work of a NGO. The groups were gathering a certain points and waiting for the convoy to pass though then they joined. It's too well organized to be random. It definitely isn't a "Forrest Gump" situation.
I saw a great post somewhere the other day that said "if immigration laws were changed so that they were no longer illegal immigrants, would you still be against their coming?"
I didn't say "let them in." I'm saying that their refusal to accept job and papers in Mexico shows that they're not interested in really working or being productive members of society. People will see this and go "huh, maybe we do need that wall" or whatever goes through their brain. Point is that this latest bit will only end badly for the left who is generally for letting them in.
