IMO, the Reagan Administration was the threshold between capitalism and corporatism. In capitalism companies only succeed by building a better product, or finding a better delivery method, or more effective marketing, or something that leads to a real or perceived benefit for the consumer.
In corporatism the path to success is to develop close ties with the government, then leverage those ties to create a strategic advantage. The telecom industry has done this by lobbying Congress to pass laws which make it harder for local communities to build their own broadband networks. Other examples include large financial regulations who lobbied Congress for stricter reporting requirements which forces out the small players who can't spend the money on compliance.
Reagan was the crossover from capitalism to corporatism, and America has been trending downhill ever since. Trump is the absolute worst thing that could have happened to the economy because he's corporatism on steroids.
