The fact that the weak are forcibly propped up by the strong, and that unity has been substituted with societal prostitution, is what will lead to the death of the 1st world. Complacency and the inability to function or change is not a trait of fitness. With a lack of fitness comes either extreme circumstances where the strong adapt get rid of the weak, or the whole species dies off and is replaced. The whole hard times-strong men-easy times-weak men thing.
