That's because it hasn't happened. It is simply a highly-plausible fantasy used to justify government interventions in fully-functioning markets. Economist Thomas DiLorenzo has actually studied this, and has found that, in the vast majority of cases, monopolies are associated with a dramatic (edit: permanent) reduction in prices. He found only two cases that actually followed the "predatory pricing" script (edit: that is, where prices dropped over time and then rose when monopoly power was achieved) — and those were trivial monopolies in the markets for matches and castor oil in the early 20th century. (Edit: remove FTC comment, as it is besides the point and not strictly accurate)
