Well, no one here seems very impressed with my missive on why it is happening.

Boo hoo.
But that won't keep me from tooting my own horn, hell no one else will.
What to do about it? Nothing, squat, diddly! In my theory (which just happens to be brilliant and right!) there is nothing to be done about it because it is part of human nature. Observe and ponder.
All joking aside, the thing to DO is to understand how human nature operates and prepare yourself for what comes next. At this point it really doesn't matter much how much money the rich have. The money only exists in the current reality, in the current economic situation. When this situation changes the heard/school/flock will change on a dime and then there may well be some kind of revolution.
Money exists only because of trust, the trust that J6P puts into the system. Big Men are rich because they represent our collective self image. When that trust fails, then J6P will likely be plenty pissed, he will knock the noses off all the old statues. We will want to show just how different we are from those old gods. The pendulum will likely swing far to the opposite extreme. Best to be scarce during those times. From that a new reality will emerge shaped by a new economic and environmental situation.
Trying to FIX the current reality is like trying to reduce carbon emissions. Can't be done, not because it is not technically feasible, but because we lack the collective wisdom to do so. Even if we fixed the system we would just prolong it.
No predictions on when it will collapse, although I think that 2016 will be a critical year due to the political situation.
