I personally believe that lots of Americans care, which is why Americans send donations when people in other countries are in need. That said, I think Americans are tired of being manipulated by those motivated not by ‘caring’ but by their desire to shift demographics so as to obtain and keep power.
The question that should be asked is ‘why do these poor children have to leave their countries of birth in order to have good lives?’. If children from the US were being taken by their parents (or other adults) to foreign countries in order to have better lives, there would be an enormous outcry about America failing its citizens and its children. Why is a similar outcry not being directed at countries like Mexico, Honduras, etc.?
Most care more about these kids in Thailand than they do about S and Central American kids infiltrating our country, illegally
