2,000 years ago people born into wealth and power fought amongst each other for leadership and control while the population simply learned to live with the results. The only thing that has changed since is that the process has been optimized: less bloodshed, less constant dramatic upheaval, the hills and valleys leveled a bit. This benefits everyone, including those on top. But let's not pretend we're engaged in some grand experiment for the betterment of mankind. We're living in a plutocracy. Always have, always will.
