Your grammar makes no sense. But anyways point is 19th century America, and early 20th century America was unsanitary much like China today. Its a product of industrialization. Some more developed Latin American countries have high life spans(ex: Cuba), and are hygienic. Others that are still developing have sanitation issues. Any developing nation though has gone through that. Also its not as if Latin America is all poor. There are big divides in development within the countries themselves. The big cities in Latin America are well developed, but the more rural less developed areas still are impoverished. Same phenomenon in Asia. The big cities have their own issues because of the rapid population growth to the cities has led to the development of slums like favelas in Brazil. Europe for centuries was unhygienic. Most people didn't even take baths until the 20th century. Part of this is cultural. Places like Japan have traditionally been hygienic. What is your point though about other Asian nations that are less hygienic, and violent? South Korea is modern, the people are very hygienic, as are some more developed Asian nations like Taiwan. The lack of sanitation is more of a product of industrialization, and pollution in my opinion. Northern Mexico is dangerous because of the drug trade, and the same is true in Central America that boasts the highest murder rates in the world since these countries lie between Columbia and Mexico. These problems are interrelated with the US because these drug cartels biggest market is the US. If there wasn't a demand for drugs in the US there wouldn't be as high of a level of violence in Latin America. Those who do join drug cartels are usually poor, and uneducated. People who turn to crime usually are poor, and uneducated. I find it awkward that in your attempt to defend Hispanics you ended up being racist towards Asians, and White Hispanics. Its true Northern Mexico is more White than other parts of Mexico, but Southern Mexico also has a lot of issues with the drug cartels(see the violence in Acapulco).
