"Global culture" is of course not a culture: it's the global marketing and imposing of commodities and images for the interests of the few at the expense of the many.
The modern world seems to have no notion of preserving different things side by side, of allowing its proper and proportionate place to each, of saving the whole varied heritage of culture. It has no notion except that of simplifying something by destroying nearly everything.
I am so spoiled. I cannot watch a show where it gets interrupted for ads. I have to TiVo it and skip through the ads, because the culture of advertising is so false and phony that I just... ugh, you know?
Culture is the one thing that we cannot deliberately aim at. It is the product of a variety of more or less harmonious activities, each pursued for its own sake.
