Helping or making things worse?

I was watching The Lost Boys of Sudan and that brought to the forefront something I'd already been pondering. Are we really helping when we bring refugees over to the US? I mean, yes, if there is genocide and persecution, we need to do something, but is taking them out of their own culture the best solution? They end up losing so much. I have been friends with and/or worked with refugees from many countries including Iran, Sudan and Afghanistan. All of them wanted to go back to their country, at least at some point. I don't know how much it costs to relocate refugees etc., but I wonder if that money wouldn't be better spent assisting their home country with whatever problems are leading to an unsafe environment. I think we also have it in our mind that quality of life is based on things like electricity and carpeted floors, when many people would be much happier in a mud hut with their own tribe, with their family, in their own culture (so long as they were free from harrassment, had clean water, etc.). Adjusting from that type of life (and communal living) to the US is not easy and not necessarily pleasant or better. I don't know what the solution is, and I'm sure that this has been analyzed by people who know a lot more about the subject than I do. Of course, I fully believe that refugees who come to the US should be welcomed and assisted, but I just don't know that they are really happier here. I think there has to be a better way to do this. I feel similarly about the illegal immigrant issue. Obviously, the US cannot support the entire population of various countries. They cannot all come here. However, if the Statue of Liberty and its inscription ("Give me your tired, your poor,/ Your huddled masses yearning to breathe free,/ The wretched refuse of your teeming shore./ Send these, the homeless, tempest-tossed to me,/ I lift my lamp beside the golden door!") is more than a quaint poem, we need to open our hearts and our country to those in need. With the illegal immigration issue, most Mexicans who come to the US illegally come because conditions in Mexico are very bad. Instead of spending so much money trying to keep them out, I wonder what could be done to address the conditions in Mexico that lead to so much poverty and lack of job opportunities.
