Many illegal aliens have died over the years while trying to enter the USA illegally. Some by exposure or other natural causes, but some at the hands of border police. The democrats will be happy to hand you a list of those who have died. So this tells me that not only is the USA superior to Mexico in every way, including culture, laws, government, and other areas, but that Mexico is indeed a s***hole country, as some have said. When citizens are willing to risk death to escape a country, that is a s***hole country my friend.
The United States is objectively superior to Mexico in many ways. I would not go so far as to say that it is superior in
every way. Mexico has a Catholic patrimony that the US lacks, unless it would be certain regions (Louisiana, Midwestern cities such as Cincinnati, St Louis or St Paul, rural New Mexico,
et al). Mexicans are very family-oriented and value time spent with family and friends --- it's not all about working and money, as so often happens here. The pace of life is slower. The cost of living is far less.
The litmus test is to look at what countries people are lined up trying to get into, and what countries people are lined up trying to get out of. I have seen people lined up around the block, literally, at the US Embassy in Warsaw, desperately hoping they will be able to get a visa. I don't know how true that is these days, with the EU and freedom of movement, but it was definitely the case in the early 1990s shortly after the Iron Curtain had fallen.
