"Why is this? Why can't they make money selling movie tickets?"
Maybe they can. But they do what will make them the most money.
Irrational people like you are more likely to go to the threatre if the ticket prices are low. Irrational people like you are more likely to buy overpriced concessions if low ticket prices get you there to begin with.
It is this way because of the psychology of stupid people. Theatres make more money with this model. Smart people like me bring in 6-packs and fast-food in their girlfriends' purses.
It's win-win. Smart people get cheap tickets and dumb people pick up the tab. Isn't this the biological evolution you support?
You're making a big deal out of something which is the result of free markets and human stupidity. It supports absolutely nothing of the nonsense you're spamming about here. That you think it does is just sad.
"The equilibrium in price in the new economic paradigm would be attained and maintained by your neighbor's decision to accept your offer of 2 heads of your garden's lettuce for 3 of his apples or his other neighbor's offer of 3 oranges for two heads of his other neighbor's lettuce. This price equilibrium would be determined by your decision to trade your lawn-mower tractor for Jake's RV for the duration of your family vacation...."
Blah blah blah blah, huge wall of text, all nonsense like this. You're proposing an economic barter model (which we rejected because currency is mega useful) in which the price of lettuce is determined by a lawn-mower trade?
That's ridiculous. Additionally, implied in your example is a scarcity of goods we don't have now. Everyone who tries half hard for half their life can have all the lettuce and apples they want. They can invest in an RV when the time's right if they make good choices. Your example is predicated upon a presumption of poverty--a move backwards--and complete ignorance of the hassle and injustice present in a barter economy.
Why spam? Nobody can remain ignorant of why currency is awesome and barter economies suck. You have the internet. This is just more trolling.
