Solution for a better world

How much money does one person need to live comfortably? Let's assume it's $10m.
Once a person's assets has reached that amount it should be capped.
Any additional income should be given to the company's shareholders or kept as its reserves.
The income to the person should be given just enough to maintain his net worth at the capped value.
By limiting eveybody's assets to $10m, wealth can be distributed more equally to society, thus benefiting everyone.
No one gets to hoard massive amounts of wealth. Improvement in productivity should benefit the whole society not just to make a few filthy rich.
