I really do not understand your Chinese mentally. Not everybody date somebody based on their wealth status or background. There is something called purely physical attraction. Also there is something called hook up to fullfill physical desire at that time without any further dating intention.. That why you call it one night stand. I know material is the KING for mainland Chinese whoever you pick to play or to make friend with.. But this does not apply to a normal people around the world. I know a lot of Asian prefer Caucasian partner because they purely find them handsome, well built, attractive & click well not their $$$.. There is huge cultural gap between mainland Chinese and the rest.
