> But what is the minimum size for a business to "get so big they have taken over control of regulation"? This is sort of like asking, "What is the minimum weight you can put on a seesaw before it tips?" The answer depends entirely what's on the other side. One way to look at free markets is that they provide economic stability in the same way that tensegrity [0] structures provide physical stability. They work not because any element provides stability, but because — when very carefully composed together! — the elements exert opposing forces which all balance out leading to a stable system. The "brilliant idea" of markets is taking advantages of forces that already exist — human selfishness and the desire to profit — and harness that to produce a system with some level of efficiency. The downside is that there's no real way to evaluate market participants in isolation. [0]: https://en.wikipedia.org/wiki/Tensegrity https://en.wikipedia.org/wiki/Tensegrity
