Taking it to a broad level... I think this line of thought has influenced just about every aspect of our current reality, starting with when we had evolved to becoming consciously aware of ourselves or "cognito ergo sum." I view the world that we live in as a dangerous, dynamic "tug-and-pull" between collective groups of people with enough power to exert what they think our world should be, of what it should value, what it should exclude, how our society should be structured, and how normality should be defined. People may say that there is nothing an individual can do to influence reality, but depending on the support one could rally, our reality is very much influenced by groups of people in positions of power who may or may not share the same ideas that you do on an individual level. Issues can be either solved or exacerbated depending on what ideas, values, and opinions those groups of people hold.
