Two interesting developments which will dramatically increase income inequality:
Cheaper Solar Panels will make solar power dramatically cheaper
New Capacitor Batteries may make internal combuston engines obselete
If these two developments prove to be profitable innovations, the investors in these companies will be fabulously rich. Possibly the first Trillionaire will be a result.
The rest of us? Will be rich by many multiples of Trillions. NO ONE will be poorer and EVERYONE will be richer and many future generations of entrepreneurs will be inspired to seek even more profit etc etc etc.
