I also believe that it is our duty as society to make sure everyone can have a decent life even when not granted the same privileges others get for free.
Assuming everyone can put in the hard work and make it, you imply that everyone has or can learn "quickly" a markeatable skill, including the business acumen, the available free time and the mental/physical health required to succeed.
But the real issue is that even if everyone was able to try to get rich starting on an equally levelled field, our economic system can't allow everyone to succeed. We need poorer people to do employed jobs in order for their value produced in "excess" to be sent to shareholders and CEOs.
It just seems madness to me to have this global competition where the poor race against each other in order to be allowed to become one of the rich. We can do way better than this.
Competition is great, but at all levels.
Wealth creation is not zero-sum. Read PG's essay: http://paulgraham.com/wealth.html
