I like to play MtG, and some of those cards are expensive as fuck, while others cost pennies, but they literally are all require equivalent amounts of labor. I also saw a Louis Vuitton dice case that costs $720. I’m no expert on dice cases, but I highly doubt it took significantly more labor than any other dice case I could buy at Walmart. Also how does artificial scarcity affect prices, and how does that work with LTV? Like, amiibos, for instance, iirc, are very expensive simply because Nintendo doesn’t want to make very many.
TL;DR why come some things so expensive? Even if they use the exact same amount of labor as less expensive things?
There are two different values here, the values of the means of production and labor power (a.k.a. constant and variable capital, c+v) and the surplus value (s). What you’re noticing is that having monopoly/oligopoly power and “intellectual property” (a sort of protectionism) lets capitalists increase the surplus value without changing c+v.
Marx’s LTV says that labor created the surplus value s, not that labor will be paid for it. The surplus value is the unpaid value created by labor. Basically capitalists are using their monopoly/state power to exploit labor more severely.
