Whoever can't, dies. That's how all other species do it. Some species help each other out a bit, but not to the extent us humans do. But isn't that because they can't? They don't have the bodily tools we do, after all. Even monkeys don't have the brainpower we do. I've watched ants. If all humans did what they did, willingly, as much as they were able, this earth would not be able to contain the population explosion.
