That's certainly not true. I'd be curious to see the reaction of you telling a woman who is satisfied with her life that she's wasted her potential.
There are people out there who could make meaningful contribution to this profession. There is a demand for people who could make a meaningful contribution to this profession. There are artificial barriers, based on gender/race/class/whatever that make it marginally harder for some people to contribute.
A more concrete example: The unemployment rate in my country is very huge, and yet my organization is still having a hard time finding talent. Is it because none of the millions of people looking for work could possibly do what I need done? It seems more likely that the complex system of forces has dissuaded talented people from getting skills in this profession.
