Suppose we did exactly what you suggest, preventing amassing incredible wealth.

The only substitute for wealth is power and for power is wealth (with a hefty conversion fee). Amassing power would be the alternative action taken by the driven billionaire types if you take away the possibility of amassing wealth.

A bunch of stymied billionaires amassing power leads us back to pre-nationalized Europe.

At least when people amass wealth, they generally do something valuable for others.
