Surely, human beings have been gifted with consciousness and intellect which doesn't depend on their economical background or status in societies. So a person living an average life can come up with great ideas by using his intellect and brain when he thinks deeply. I guess there were lots of people who thought about gravity before Newton too, they just couldn't put into paper etc. I guess if money and wealth is distributed evenly and on merits, many people with great ideas can implement their ideas on their own rather than depending on someone with too much resources.
