Dismissing a 100,000 foreign individuals crossing your border as "a bunch of kids" is even more disingenuous and further fuels the issues the anti-immigration folk have. 100,000 is not peanuts. As the other commenter mentioned, that's a bigger than probably hundreds of towns in the USA.
Anywho, if we really "cared" about all the "bunch of kids" suffering in Mexico, we would have invaded Mexico and installed a "democratic" government years ago.
