The system we have now is far from perfect, and it's being changed with every passing moment by more forms of automation. However, it's a system that was able to take a species of this earth and raise it out of the dirt to be able to mostly conquer its domain - and possibly the solar system and outer-space if we play our cards right. While some people who have gained powerful positions through their abilities (or their forefather's) have abused them, many have not. That said, "survival of the fittest" is still in some part responsible for the great achievements of mankind which has benefited civilization as a whole. What's interesting here is that with your plan, those achievements may end up being its downfall too. A slow slide into mediocrity is the fastest way to lose our grip on the controls of our own destiny. Barring an asteroid, super-powerful alien race, or spiteful deity, I like our chances playing the long game with what has (mostly) worked until now.
