There are different levels of suitability for everything, including scientific and technical innovation. Combine advantageous intellectual predisposition with a "privileged" education, and you may get a "genius". I appreciate these people, but I'm more impressed by those who excelled (even if to a lesser extent than their aristocratically educated contemporaries) against all odds. Especially when the underdog is working actively against their disadvantages instead of lurking on forums pasting about the unfairness of society and the plight of the proletariat.
