"we live in a world in which the richest EIGHT people have more wealth than 50% of the population COMBINED."

That's exactly what happens and what you expect if you let money flow freely. Those who can make good trades secure a higher share of wealth which they can invest again to make even more money. As a result of this process, more and better paying jobs are created and the wealth generated by a growing economy is passed down to the workforce. Stating that there is anything wrong with free-market capitalism, just because there's rich people out there is nothing but marxist sophistry.
