That's vast exageration and it's sad people believe this common myth about China, lived there plenty of years and yes, it's common phenomenom, but so it's marriage out of love. I knew plenty of mixed couples and also plenty of local couples who contradict this claim. Pretty much none of my foreign coworkers had house or car and married if they wanted (yes, some traditional parents were not happy about it, but it was usually more about being foreigner than wealth) and so did Chinese couples doing naked wedding. I really recommend to you explore term "naked wedding" (it means without house/car) which is more and more common since properties in China are more expensive every week.
I find personally this selfpity about how you are screwed if you are not making tons of moeny and havin great car and house a lame excuse, as if all girls living would be gold diggers, but I guess in this website where is maybe 98% readers men it sounds plausible in this echo chamber.
