Perception, by definition, lags behind events. The leap of thought that wraps us around an issue like the 1% of us controlling almost all the wealth is reminiscent of watching a chemical process, like a chemical indicator of an element in fluid, when the liquid stands for a moment, and suddenly, at the point of saturation, changes color; or better, we see it change color.
This quantum leap involves perception insofar as the leap is with the perception, not the event. The extent to which the powerfully wealthy have controlled social events is obviously historic. Why the sudden attention? Limits have been reached, that's why. The limits may be to perception, but the effect is the same. We wish to amend our financial system, put brakes on it, steer in in a different direction. We do it all the time actually, in subtle ways few non-professionals can perceive.
The fact that money makes money is the problem and the genius of capitalism; and capitalism is inevitable as a system, as long as wealth is represented in abstract form, whether or not it's tied to actual physical entities apparently, since the gold standard is a thing of the past. The Muslims seem to get along without interest, reportedly. I wonder how? Certainly, without respect to the resources involved, wealth inevitably accumulates in one place; and since in some sense its total worth is arguably fixed, this accumulation results in a lack of wealth elsewhere.
If we lift the discussion above the digital, and you care about the humans involved who may suffer from this equation, it would seem that the wealth-accumulation process must be tailored so that the flow of wealth more righteously returns to its source: the LABOR that produced it in the first place.
We could, using the body's blood flow as a metaphor for the flow wealth in the social body of a healthy society, find glands and organs that equate to the Stock Market, the Banks, Investors, Politicians, Accountants and Investors, and all the stopovers that might make the detours of wealth in society legitimate. But in all, official Quotes referring to movements of wealth on these abstract planes are subjective, relative statements, created from previous statistics that themselves were unreliably communicated; so creating those reports from Wall Street or elsewhere must be like playing handball in a court with moving walls.
Also, observing and reporting on ourselves is a process doubly weighted down by the Heisenberg Uncertainty Principle, which states that observations are inevitably skewed by the observer. In other words the results when we look in the mirror are tainted with subjectivity, as it's Us, ourselves, that we're looking at.
Not setting limits on wealth is like not setting limits on the height to which a building may ascend. Somehow height has been equated with wealth and power and success, and we applaud it. However, without limits; it's totally predictable how the bottom line works out. Once money begins to flow in a direction, it's all downhill, or uphill, as may be; from there; because wealth, as our system is now designed, must create more wealth, or move to hands that will employ it, or it might as well evaporate... that's the rule.
So when the wealthy run out of good ideas, they turn over their bucks to a wealth-accumulator and are detached from the actual spending and investing intelligence that directs the flow of cash. However, their money keeps accumulating, unless it's miss-invested. It doesn't change their lives, because beyond a certain amount, money can't buy the things that make life worth living.
Growth is endemic to life and likewise to all of its expressions. The metaphor ends when enormous wealth is inherited, as it would be the equivalent of eternal life for one organism, instead of the typical worm-food to grass to cow to milk etc.
Perhaps inherited wealth that exceeds a certain limit might be divided among the needy, deposited into a low interest loan source upon the death of the Owner. Whatever we do, it should support the flow of money in the same logical way the body does: Nothing, no part of the body is deprived, for to do so would cause the whole body to collapse. It's just science, the hardest working parts of the body get the circulation, the brain, the feet.
Do this experiment: put a tight rubber band around your wrist and see how long you can stand it. Left in place, your hand will fall off, and you will die. Suddenly the logic of sharing wealth becomes obvious: good old "enlightened generosity" because enlightened selfishness doesn't exist in Nature. The deprived parts of the social body, aware of their deprivation, will take their due eventually; even if revenge is their only option and destruction their only effect. That too, is inevitable.
