Why doesn't Mexico take care of its own people? Why don't the ultra-wealthy Mexican elites help to pay for the health care and education etc of their own poor? Why do they instead encourage their poor to leave Mexico and invade the United States? Nature provides a parallel that is instructive.
Some species of birds thrive not by carefully rearing their own young, but by pawning that task off on adults of other species. The European Cuckoo, whose distinctive call is immortalized in the sound of the "cuckoo clock," is the bird in which this habit has been most thoroughly studied. Female European Cuckoos lay their eggs only in the nests of other species of birds. A cuckoo egg usually closely mimics the eggs of the host (one of whose eggs is often removed by the cuckoo).
The host may recognize the intruding egg and abandon the nest, or it may incubate and hatch the cuckoo egg. Shortly after hatching, the young European Cuckoo, using a scoop-like depression on its back, instinctively shoves over the edge of the nest any solid object that it contacts. With the disappearance of their eggs and rightful young, the foster parents are free to devote all of their care to the young cuckoo. Frequently this is an awesome task, since the cuckoo chick often grows much larger than the host adults long before it can care for itself. One of the tragicomic scenes in nature is a pair of small foster parents working like Sisyphus to keep up with the voracious appetite of an outsized young cuckoo.
The folks coming up here are dark skinned, mostly Indian Mestizo. The elites in those couuntries are mostly white- take a good look at Vicente Fox. They’re exporting their race problem.
