Well i dont mean to be rude or anything but when we allow hundreds of illegal immigrants into the US, it makes the country more crowded. Of course some do a good and work etc. but lets be real. Many, NOT ALL, hispanic families are really big and they end up having on average about 3 children whereas the average for most other people is 2 or perhaps 1.5.
I dont have the statistics but its a known fact that the hispanic population is growing so fast that they might one day be the majority (i forgot the estimated years but its not some huge number). I have tons of hispanic friends and even some of the closest people to me are hispanic but at the rate americans consume, we cant really afford to let in illegals regardless of their situation.
Like i said before, we have no obligation to feel for the poor conditions elsewhere. When it comes to wellbeing, the initial americans come first. I dont think we should completely ignore the fact that people are living in such conditions but overpopulation is always a problem when we consume as much as we do.
