You could argue that the point of creating an oligopoly and then squeezing customers after the fact also is adding friction. All value creation is not great for the people. But it is hidden under the name. Financial engineering and rent-seeking are getting quite advanced nowadays, because of the political class.

I like the idea of classifying it into four buckets: those that are below tax net gains for a country, those who are above and those that are above the tax net gains using just their wealth, and then the government.
