Not necessarily, as a counter argument consider some of the giants such as Michael Faraday (physics and chemistry) and Bernhard Riemann (Mathematician), who were born into poverty and later in life had many conflicts with the people that would be considered elitist. (Especially when the elitist believe that they were better and that people such as the son of a black smith should stay away (a crude summary of some conflicts in Faraday's life). Riemann died of TB, a common infliction of poor people (not elitists).
