That discounts history far too much. We have more competitive markets today because of antitrust regulation passed over 100 years ago and vigorously enforced up through the 90s. Tech would be more competitive today if the DOJ had completed the Microsoft prosecution instead of settling.

Our markets are becoming less competitive today because of government action due to regulatory capture - the intentional weakening of the regulatory state from within. We need more powerful, dedicated regulators in order to maintain competitive, free markets.
