My partners friend, let's call him Tim, is married to a Filipino woman he met while working in the ME.
He'd previously struggled to get a partner.
He also displayed very unpleasant behaviour when his friends got partners (only to the partners, not his friends).
She had a decent enough job there in hotel hospitality/PR type stuff, but obviously nothing like his 6 figure engineer salary.
She was described by one of their group of friends as looking like Miss World, and a distinct contrast to him, as a pale, pasty, overweight and not particularly conventionally attractive guy.
She probably would have been clued in enough to guess his income/potential income, but in any case the attitude of many women in her group of friends was illustrated clearly when my partner (then single) moved there for work, was introduced and her friend asked her what his salary was (which she then reported to Tim who reported it to my partner).
When in an ltr/marriage with Tim, she has instituted "deals" like, he gets to game for a certain no of hours a week if she gets an expensive designer handbag.
My partner said a lot of her focus seems to be on gaining lifestyle items to impress and compete with her friends and family.
I think Tim also helps out her family financially (which is par for the course for lots of families from SE Asia etc).
She is supposedly devoutly religious (Catholic).and when she found out my partner is a Protestant was shocked, declared him not a "proper" Christian, and banned him from a proposed church Christmas ceremony. She/they have also done something a devout Christian would not do, which I won't go into, but is significant.
So I suppose in a case like theirs, it's rather mixed.
She could have continued trying to get promoted and earn well herself in the ME, but getting a 6 figure salary man was easier. She runs their marriage (and all their friends agree she runs it) like a business/trade. She has some rather unpleasant, immoral sides. He's a bit of a dick too, so they kind of suit.
I don't know what her partner etc. choices in life would have been had she not been born in a developing country with poverty.
For the most part however, the advantage taking (of poverty, lack of opportunity, deprivation etc) is definitely on the bride buyers side.
