So hes talking about conditions that aren't reflected in the real world... ever? Well damn, I wish someone had told me I could get rich from making up a theory with conditions that never occur.
assuming perfect competition is a simplifying assumption that neoclassical and classical economics also do. that's because, if you don't make that assumption, you'll have to come up with a complex power theory to explain prices under a variations of bargaining power caused by a variety of factors.
this is ultimately the problem with *all* theories of prices.
And yet it still has value. The Austrian subjective theory of value explains all prices, not just ones under conditions of perfect competition and only for "readily producible commodities".
haha. the "subjective' theory of prices doesn't explain prices.
for Marx "value" is understood in terms of society's investment or cost in producing something. not subjective "evaluation" of something.
I'm not here justifying Marx's view. just explaining it.
The starving man does not value ipods, TV's, or even mansions, the starving man values food,
and if the starving man has no money he won't affect food prices at all...and he won't get any food unless someone gives him some. in other words, it isn't "subjective evaluation" that shapes prices but power, and the money you have available to you gives you a relative form of power in markets.
thus in a region where the jobs mix changes so that there is a higher proportion of professionals and managers making high salaries will see problems of gentrification as the increase in people with high salaries will enable them to outbid working class people for dwellings. the working class people don't suddenly value their dwellings less. it's just that now the prices become unaffordable to them.
The car is more expensive than the lamp because cars are valued more highly than lamps.
This is silly. If people valued cars less, at some point cars wouldn't be produced. That's because what people would be willing to pay would not be enough to cover the costs of production. On your theory, the prices of cars should just keep going down as "subjective evaluation" falls.
The emancipation of the working class must be the work of the workers themselves.
