I think that at birth virtually all normal men have the potential to run a sub-5 mile at some point in their life. However I don't think you can take the average American male aged 18-30, train him for 6-months, a year, or what have you, and expect him to break 5. The problem is that most people, especially in a country like the US, just don't have a running background. Either they didn't play sports as a kid or they played sports like football or baseball that didn't involve much running.
Even with as much evidence as we have, there are so many "runners" who think a sub 5 mile is easy for runners in the general population to do.
Compared to a 4 min mile, 5 is worlds away. But even reaching 5 is beyond 97% of "runners". Just take a look at the massive amount of running data available online.
By the way, only about 1100 runners have broken 4 min since 1954.
