If Mexicans Can Travel Visa Free to Canada/Europe/Asia why they choose to go to the USA illegally & Unsafely?

Innocent soul, believe it...we can. I think is probably because historical migrations has developed a net of support among those who have established before. Besides, we have an historical relationship as country, and our values are similar, is not the same with europe.

Well a 1958 Chevy station wagon converted into a raft will only go so far...

well have you ever heard the sentence "the american dream", US has like a shine for them, but they go to canada and they stay there also, but you know something, canada its not a very popular country it is really really good but not everyone knows about them, also in some parts of canada life its more expensive than in us, and remember mexicans leave to provide a better life to the family they leave, so they need to be able to send more money, because us money its more worthy than canadian most of the times, i think its the same with europe.

It's due to the perception that there is a large hispanic and spanish speaking community here in the US especially in border states like CA, AZ, NM, and TX. Also, as someone has pointed out above, there are historical ties between the two countries and also Mexican immigrants (both legal and illegal) tend to have family members, relatives, or friends here in the states that can assist them in fiding jobs or place to live once they arrive, unlike in the EU, or even Canada.

Canada. -40 degrees. Mexico. Tropical. See where there may be a compatability issue?

i donot think that they are allowed to travel in these countries visa free.

Is this a serious question?

That's a good question and I have no idea. At first when reading your question I thought "well he just made that up, I can't believe Mexicans can travel to the EU without a visa" but indeed they can come to the EU with just a passport and without a visa. While that's pretty baffling, it is what it is. Back to your question, like I said, I'm not sure. Maybe the US is simply closer and you don't need a plane to get there from Mexico, so that makes it pretty convenient, if risky. Then there's the climate. The climate in the border states of the US is a lot like the one in many parts of Mexico.

Why would their standard of living be higher in Canada or western Europe? The avg. poor American is better off (car, TV, consumer goods etc.) than the avg. European (that's avg. European, not avg. poor European).
