No! There very much is an arms race. (There were studies about how many man of each generation got to procreate.) You have the most beautiful women in relatively poorer countries. You have women in the industrial world complain about the lack of real man, and run to those of other cultures who are perceived as more manly. You have a few males getting most of the sex from active non-married female crowd, and you also have unhappy 40yo virgins.6 You need to be relatively better than those around you. Which leads to interesting results if you act in male dominated fields :-). Naturals are not naturals by birth. They develop and hone their respective skills at some point and get a lot of practice in it. Likewise being inept is not a life time curse. You can learn things later in life too, assuming there is useful material available. But you do not need to become a complete master of any particular domain. Just good enough to get what you happen to want.

The point i tried to make above was another one. If someone is incapable to speak correctly he can go to a doctor and train. If someone wants to improve his vocality he can take acting classes, learn the ways actors use to speak varied and understandable. Which is good. If you are unhappy with your social life you can do very much the same. If a PU book then tells you to take acting classes to learn to speak better it does not suddenly become evil advice. It is the same. Just from a different source.
