Well, the examples of Rockfeller, JP Morgan etc. only show the "tip of the iceberg". What, in my opinion, is underlying is a probability distribution of people wealth.
In times of big changes there is more uncertainty, which increases the variance of the distribution. It is true that these times bring out people that make enormous wealth, but also many people remained poor.
And those who orient better in the situation(or get lucky) end up being better off at the end.
