So is there anything to the pairing of 'economically reasonable' with abandonment of 'we are all created equal'?
prod, prod.....
How does that apply here? Do we consider it morally wrong that United has a first class section that has shorter lines for people who pay more?
But that is not the situation here. The ISPs are already charging customers more for higher bandwidth limits, which would be analogous to buying a first class ticket. Now they want to charge the content providers to "speed up" (which is actually a payment not to slow down) their traffic to the customers who are already paying for faster service. So, for your analogy to hold true, we would see a situation where you have paid for first class accommodation, but when you arrive to take your seat you find that there is no difference between first class and coach because the airline is trying to get seat manufacturers to pay more for the privilege of providing you with a more comfortable seat.
The analogy does apply here because what a company would be paying more for is that when there is a line a company pays extra to have the priviledge of being in the shorter first class line compared to having to wait in the general class line. The get slightly better service but everybody arrives at the same destination but first class passengers are the first to get off the plane.
That's not it at all, the entity being charged extra in this case is not the end user of the product, be that airline seats, or internets. The end user has already paid to have a certain class of service provided, and has been receiving that service for years. Now, the service provider is dipping into the other end of the line, charging the user on one end, and the content provider on the other end for what the user has already paid. So, it is very much like arriving with your first class ticket, expecting a first class experience, but being told you are going to have to deal with a coach experience because the airline has not yet been able to extort more money from manufacturer of first class seats. It's so very much the opposite of what anyone should expect from a market experience, that I don't see how anyone who is not a part of the industry reaping the profits can defend the practice.
