Ok, you win at sarcasming.
The only thing is that you should never force others into this system. I am not against reasonable prices, I am against forcing them on people. If the owners of companies want to be assholes, let them. Then people can go shop at other stores/whatever the specific company is involved in.
Alternatively, if enough people are pissed off about prices on a certain good, go ahead and start a company to build it cheaper. If I think it has reasonable chances of success, I would sure as hell (maybe that's a bad example) invest in it.
But the thing is, there are no "other stores" to go to when you're talking about pharmaceutical companies or airlines. You want it cheaper, you don't go to any of them. The airlines hold a oligopoly (thank you Wikipedia for this word), as do the pharmaceutical companies.
You want more examples of this? Steel, electricity, internet access, cars, airplanes, mining, agriculture, publishing, the list goes on and on. You can't start up a company in those examples, don't ever try. It's an oligopoly, so unless you feel like completely changing the economic principles of the US, don't bother. The few things that aren't included in this include the arts, and gaming. The actual publishing for those is where it gets difficult, except when you can digitally publish, where games are the most successful example.
