I'm from a mixed cultural background, so I see things a little differently to many Australians.
I've been seeing a Belarusian lady for a while. I always pay - and I'm quite happy to do so. Given who she is (which shows through on many levels, which are all consistent and genuine), it has never really occurred to me that it should be any other way (it's also not an issue financially, which probably contributes to my view). Had she been brought up in the average Western society, or had her personality been less natural and genuine in this area, I would have had a completely different view of this arrangement...my view is that every difference should be viewed in its own context.
I will of course say that she is spoiled (and she admits that too)...that may have some to do with her looks, which are absolutely stunning (though it also has to do with her parents)...
...which brings me to a comment made by maxdancona on men being prepared to pay for the most desirable women...
I wonder exactly how much of a contributor that is.
Then again, her looks weren't really what attracted me to her in the first place (longish story that I'm not bothered going into), so it may have little to do with it.
