Exactly. If you ask anyone on the street, "is it easier for a fast food worker or a business-owning millionaire to make their next million dollars?", common sense will prevail.

Money begets money (and power). It doesn't require an economics degree to understand this positive feedback loop.

Wouldn't that be more of a negative feedback loop? My signals and systems class was a long time ago, but a system that throttles to extremes is negative, not positive feedback.
