I can't agree with your two example.
In your first example, Tom, Dick and Harry are effectively buying 3 different products. As an "early adopter", Tom is paying a premium to get the product on release day. Dick is paying standard price and the publisher still makes a profit. Harry may be rewarded for his patience with a discount, but only if the publisher wants to shift old stock at a loss to make for new, premium priced stock that Tom will buy. The segmentation is timing, which consumers can easily control, rather than location, which they can't.
Your second example is more compelling, but still misses the fundamental hypocrisy of "them corporates" that demand the right to impose trade barriers when selling their products, while simultaneously decrying any attempt to impose barriers/tariffs/restrictions on their ability to shop around globally for the cheapest materials/labour. Does the Indian student's father get paid more for the products he makes for the western markets or does the premium go straight to the western shareholders? Does the American student's father get made redundant because he can't compete with his Indian competitors, thanks to the "western premium" on his cost of living?
