You ignore the fact that business operation in many sectors are localized. I don't have numbers, but my impression is the said companies like verizon, healthcare provider, power suppliers all have regional stronghold where their market share is easily a dominant one. I used to live in a valley in west Massachusetts, where you don't have any options to choose from for power supply(believe it's a government regulation issue) so basically you are locked up and have no means to curb the ever raising rate.
