Cross-Country Gen-Xers

Something I was thinking about recently, that occasionally pops into my mind, is why it is that Gen-Xers seem similar, even across country lines. Maybe this is too hasty, but the examples I have seen, show that there are common traits between American Gen-Xers and people from the same age group that live in either England or Australia. It may be simpler than I thought, since the three countries share a lot of culture, but also because during the 80's (part of the developmental time of Gen-Xers), a sense of world-wide culture was beginning to take off with the advent of more technology being integrated into people's lives.

That is not to say that the Internet was widely used then, it certainly was not, since it didn't really exist for civilian use, but they didn't call Gen-X the MTV generation without a reason.
