It is just not sob stories it is a fact of life for millions. When we look at the numbers there could be untold social and economic consequences for untold millions. We know one problem for instance in the african american community is fatherless homes. That has caused much turmoil. However if certain deportation or starve people back over the border proposals are enacted a similar result could happen. This time by Govt fiat. Thus increasing crime and other social problems in the long run. There are a tremendous amount of "mixed" familes out there. That of course is just one aspect of the problem and having to find a solution for it.
