There is a degree to which the most advanced have to advance in order to bring along the whole. If you've tried to push water in a bathtub, you'll see this. The water sloshes forward and, with no where to go, sloshes back to collide with the rest of the water moving forward behind it. If the advanced aren't able to move forward, their energies are diverted towards getting even more from those behind. Thwarted from movement forward, they return to compete. Progress needs a path.
This is just one of the reasons that we need to move beyond the information economy to an entrepreneurial economy.
