I don't know about the 90's but I seriously doubt any fat, white white guy could have got any girl he wanted in Korea or they would have seen him as a 'God' when I was there in 2007-9 - people were very racist and nationalistic in the main, my friends who dated Korean women got the brunt of stupid ajosshi behaviour as did I and I wasn't even dating anyone - just talking to some random Korean (female) godbotherer in the street - sure, poverty might have played more of a role back in the day but there are other factors too - there is more of a developed nightclub scene in Korea than there is here in China.
China isn't a racist and as nationalistic as South Korea but still - no random white guy is coming here and dating models and getting loads of sex - are Chinese girls easy - no decent Chinese girl is 'easy' - if you go to bars - no decent Chinese girl goes to a bar or she doesn't make a regular habit of it - so, yeah - you can get laid regular if you go to bars in China and are in a big enough city where she can be anonymous enough to be a slag, but still - it won't be quality - and most people are after quality here - that is what I read from everyone - they want 8's and 9's - no-one is pumping and dumping 8's and 9's here on a regular basis.
The great thing about China is that most of it is pretty culturally inaccessible to white guys and mongers - there is no Mexican food, no cheese in the supermarkets, no whatever makes these peoples lives happier - white mongers will always congregate in tier 1 and 2 cities because life is too hard and raw in anything less than those places - which leaves a lot of China - and a lot of women. The right guy - if he learns the language and acts with a bit of decorum will always get a quality woman here, he won't be able to pick and choose - but he will get a quality woman, better than anything back home.
I agree with you about the silly attitude some white American men have about their worth abroad - as soon as they get on the plane they are soon brought crashing down to earth in most places - most Chinese women wouldn't be seen dead with them.
As for mongering - You couldn't monger in China the same way in Prague anyway - you might be able to if you look like a local like Winston, EthanSG, Zboy1 or yourself - they could do it moreso than a white guy - but a white guy annoying passing Chinese girls in the street, speaking to them in English where I live - he would be beaten by a large posse or he would be arrested and deported - it will never ever catch on here - nor will foreign friendly P4P - could you do it, yeah? What are the chances of you running into big trouble if you don't have a local with you who knows the scene? The chances are big of being robbed, beaten up or both.
A white guy has to look like Chris Evans in order to have a shot with an AVERAGE looking Korean girl.
So most HA'ers still have a shot then...
