Do you think since the illegals are coming here ??

Do you think since the illegals are coming here this is making matter worse for Mexico ? I know they are mailing money out of here to Mexico but there work force must feel it ? So what I am trying To say if there country is getting worse that means more and more are to come is that Correct ! We can not allow that !! Is there any way that we could put embargoes on there country so there government stops encouraging them to come here and forces them to go back to Mexico ???
