Well I'm still in favour of competition, so if Ford tries to charge the police more for using their cars the police are free to switch to Toyotas. Same for taxi and courier companies. And so the general rule
commodity products would be that the price would not rise much above the cost of production.
But if Ford was to develop something better than any other car company - say, a car with the greatest acceleration - I would like them to be able to charge different price depending on whether the purchaser is the police force or a car racing team.
Nails are very much a commodity product, so once again competition would prohibit the supplier from charging much more than the cost of production. But let's say that a chemical company developed a superior adhesive such that a carpenter could save an hour on some types of construction jobs. The value of a carpenter's time is much more in the United States than in Indonesia, so I would like the chemical company to be able to charge much more for the same adhesive in the US compared to Indonesia.
