A quick look at oil company profits will tell you why. Same as banks, insurance companies, telecommunications providers, cable tv, real estate agents, media conglomerates, soap companies, pharmaceutical companies...either they exist in a protected self-regulated market, giving them a virtual monopoly...or they make something we think we cannot do without, so...the shareholders get rich and we pay.
The days are gone when making a good product and offering superior service is actually an activity worth persuing.
