Capitalism 101: Things are worth what someone is prepared to pay for them.
Generally agree but think that would read: Capitalism 101: Things are worth the price paid for them.
Capitalism has no concept of people; markets and consumers are as close as it gets.
Value is a personal judgement of worth. Different people determine what some thing is worth for themselves, which has no bearing on a successful financial transaction. At least without other influences that is. Like extortion or threats of violence.
