Sorry if my point was unclear. I'm arguing that not only does the stock market allow companies to grow too large (stifling innovation and competition), but also allowing large ownership to become too wealthy at the expense of society in general. If a company goes public I think there should be some consequences to that since it allows for this insane growth. Such as a more even diversification of ownership among the general public (aka investors on the public stock market). This spreads the wealth so to speak in a much more straightforward fashion than taxing the rich which leads to all the money flowing into the government.
