Which is amusing, given the history of anti-trust enforcement in the US. Most activity in the middle of the last century was aimed not at companies owning 95%+ of a market, but companies owning every step of a supply chain, smaller pieces of different markets. The focus was on encouraging competition, which has very much not been the focus for the last 40+ years.
