>What you really want is to ban differential pricing that uses one difference as proxy for another (namely tolerance to pay.)

Exactly! Actually, the use of proxies is probably bothering me more.

I believe this is a moral issue, so I will accept no excuses.

> a good chunk of the public would be financially unable to fly

So be it. If it was legal to steal, (probably) a good chunk of the public would be able to do things they were unable financially otherwise.

> vendors would find a way to do it

And authorities would find a way to stop it.

> Good luck trying to write a law to ban that

The government, laws and constitution exists for a reason. Laws may not be perfect but if we set the principles right, then courts may decide and laws can evolve.

What disturbed me when reading your article is this (stated baldly): You accept/describe a society where companies are trying to screw the customers and the customers are trying to screw the companies. You then try to find a solution to a problem that exists in that environment.

I think this is a more fundamental problem. I want/assume a society where *normally* companies are trying to make money honestly and customers accept that they need to pay for a service fairly (I do believe supply and demand rather than cost should set the price but charging someone more 'just because he can afford it' is not an honest practice as I see it. Also, I believe that monopolies and cartels should be regulated). Everyone is both a producer and a consumer, everyone contributes. No one should start the day thinking 'how can I screw those fellow citizens more today?'. Of course there will be ill minded or greedy individuals (as exceptions) and laws will be there to regulate and provide a fair ground for fair competition.

Airlines already have business class, first class etc. and that's fair. You pay more and you get more. Why shouldn't they be forced to find similar solutions? If you set the environment right, the right solutions will evolve. If the environment is not right to start with, all you'll get will be competition for how to rip people off unfairly.

I've probably written too much off topic. My point is that I don't find the practice ethical and so I hate it and so I believe it should be made illegal, whatever the cost will be, it will be small compared to living in a society where foul practice is legal and common.
