host: marc rosenblum.t: i think one way to think about the caller's comment is that most unauthorized democrats that leave mexico and central america, looking for work, so there is an argument that we should be investing more heavily in mexico and central america. to create better conditions, employment opportunities reasons people would want to stay at home, and reasons they would feel they had more of a chance -- choice not to immigrate. that has not really been a part of our immigration conversation. it is a little bit of a hard line of analysis for congress to go down to invest in communities so that we have less illegal immigration to the u.s. but sort of from a policy perspective, that would be a really smart investment. those dollars would go a lot farther and be more efficient then layering on more border security. we spent a lot of money on border security and we don't spend a lot of money on creating art -- creating job opportunities. host: john, you are next -- joan, you are next from tennessee.
