I think they should be allowed in, on a couple of bases. Firstly, let me make the analogy of a mutual fund. Some aspects go down, some go up, but in general people profit decently off of a mutual fund. Having widespread economies (geographically and how well the economy itself is doing) will probably only benefit the EU. And if they do join the EU, it could serve as a gateway for a more, "western" culture - so that we're not so consumed by dealing with what we see as archaic. I know this is a !@#$%^&*ty perspective but the idea that some people can be ages beyond others creates some rather complex complications. If their lifestyle is inefficient and their people choose to move towards, say a post-modern society, then so be it. Though I'd like to point out that I am completely against forcing this upon them.
