90dayfiance is a TV show about Americans using a 90-day visa to bring fiancés to the US to marry them. Usually, it is a man bringing a woman over from some other country.
I used to live in Indonesia, and I met my wife while I was there. There are advantages to marrying Asian women. I think I met one woman who identified as a 'Feminist' while I was there. She was educated in the west. Women there really value taking care of the home. I used to work in an office with a bunch of housewives and a few guys, and the women were always cooking and talking about cooking and taking care of things at home. Even though they had careers, it was a different vibe. The culture is family oriented. Virginity before marriage seemed to be the norm. Even jokes about sex were typically about married couples. It was generally accepted by the culture that wives were supposed to submit to their husbands. And there wasn't the PC sensitivity to gender issues (or racial issues) there that you sense in the west.
I was at a bus stop near a college campus a few years ago, and there was this college kid there, a girl about 18 years old or so. I asked her what time it is and said a few comments to strike up a conversation. She didn't want to talk, which was fine, but she had such an attitude. I wasn't trying to flirt with her or anything, just making conversation. But I've read that young men find that young women in the US nowadays have this unfriendly attitude when they try to start conversations. They get met with a scowl. I know what they are talking about, and maybe it was less of an issue when I was younger. I don't know. In Indonesia, if you strike up a conversation with a stranger, usually the strangers are warm and friendly. Some of the other Asian cultures are a bit more 'stiff' in some ways, but still people were generally friendly to me, including women when I was young and single.
When I was in Korea, some Korean women were open to dating foreign men. I dated one briefly. But the idea of marriage was controversial, and parents may or may not approve. I knew one expat who had eloped with a Korean woman whose parents later accepted him.
But in Indonesia, which has a lot of ethnicities and people of mixed local ethnicities, plus Dutch and Chinese mixed in, Caucasian expats are seen as desirable partners. It doesn't hurt that managers in Indonesia could earn a few dollars a month and low-paid expat English teachers could have higher salaries than them. Indonesians were colonized by the Dutch who used to be at the upper level of society in terms of power and economically. With the 'foreign mystique' a Caucasian man could go there and be considered more attractive than he is in his own country, and find women who are typically more conservative and more marriage-and-family focused than women in his own country.
I didn't analyze all this and try to find a wife abroad. I was overseas when I was during the years of my life when I was interested and looking for a wife, and God answered my prayers and gave me an excellent wife.
