Criminality is part of every culture. I'm not suggesting that criminality is a bigger part of mexican culture, because I simply don't know. I have heard news reports that there is a lot of police corruption in Mexico. Leaving aside the fact that 100% of "undocumented migrants" are criminals, by definition, I suspect that the 1.7% and 4.0% rates that you refer to are conviction rates. It is impossible to know true rates of "criminality" because not every crime is discovered or criminal caught. A higher conviction rate in one country than another might just indicate more effective policing.

I concede that some amount of redistribution is necessary, but you need a productive economy to have goods to redistribute in the first place.
