Average person is somebody who is not acquainted with science or technology. Of the total population, only a small percentage have degrees in science and technology (the percentage was even lower in the old days).
It is the intellectuals who are responsible for coming up with new scientific and technological concepts for the betterment of humankind, and so far they have done a spectacular job.
So entrepreneurs and business people who took risks and financed many of these "sorcerers of progress" are just "average" people? I think you have a rather narrow view of what societal progress means and how things all fit together. Science is just one piece of the puzzle.
