The problem with the modern economy is that companies can become “too successful” using underhanded and ethically questionable practices. They influence the government to pass laws that can strengthen their hold or eliminate competition entirely. They hide behind a wall of government when it is convenient and act like angels when the people want the government to break them up.
I don’t know what the answer is, but rewarding corruption and discouraging success are not feasible in the long term. Both arguments above seem legitimate.
