"consumer culture constructs identities"

to be honest, there's no interest in studying capitalism unless you study its mechanisms critically. and i fear yours was foucault-slop, pseudo-radical drivel that didn't even aspire to change anything. no change = no direction = no meaning.

there's some philosophical interest in the question, altho i cannot say exactly where. but if you start from a statement like that and your thesis is mostly a display of what you read, it's barely social science. it is social theory at best, and not particularly good social theory either.

the interesting questions - especially in social sciences - are the hows and not the whys. the mechanisms. that would have been more empirical and more interesting.

push it further and you'll find you're doing marketing research, which is applied sociology anyway: who buys what, and how, and maybe why, at the end.

but twenty years of foucault-slop isn't bad at all. at least you chilled.
