Modern culture might be a more apt term—but an alternate viewpoint would be, people living in huts in rural Africa probably don't have this problem.

Then again, of course, I'm sure that applies to plenty of people in the western hemisphere as well.

So, I think it could be argued that the term "western culture" is a misnomer in general, and maybe even a problematic one—but I don't think GP was out of line with common usage.
