Wanted to add to my post about looking for finance positions in the arts, museums, healthcare, academia.
1) In the arts/museums and now often academia, there are basically 2 kinds of people from a financial POV.
One is people who are actually starving artists and have little/no cushion or family money to help them, and who struggle to survive on their tiny salaries. (Even very large famous museums pay extremely badly, and 70% of all college teachers are now adjuncts making like $18K a year working FT.) These people often have another job waiting tables or something.
The other is people with family money or wealthy spouses. The trust fund folks. These are the genteel classes who originally 150 years or so ago created many arts, museum, publishing, and similar institutions (including academic), and some hospitals too, from a worldview where working for money was considered gauche but who either wanted to "give back," improve the family reputation (a lot of this was before nonprofits were a tax break) or give the ladies, who might have actually been relatively well-educated, something to do (limited to like giving docent talks or supervising their fellow lady volunteers of course, not actually making decisions.)
This attitude is kind of baked into these places still, which is why museum and publishing jobs -- which have a lot of cultural prestige -- pay so badly. When you have a nice trust fund and will be inheriting millions, your $22K museum or publishing job is basically pocket money.
This is all to say that if you are interested in finding a mate who has a lot of money herself, you could find one in the arts/academia if you screen your dates carefully and make sure not to fall in love with one of the starving artists by mistake. It can be very difficult to tell the difference by appearance, but if you say find someone in these fields who has a nice apartment and only one or no roommates, has a new car, goes on vacations, eats in restaurants regularly, and never mentions student loan debt, you could be in luck.
Yes I am being slightly sarcastic, but if this is really important to you it is actually good advice.
2) If politics matters to you, most people in the arts / academia lean left politically. Law schools, medical schools, and business schools are an exception.
In healthcare you are more likely to find conservatives, both among practitioners and in administration. Finance people everywhere tend to lean conservative.
In the arts, you are probably more likely to find a conservative POV (or at least a blandly centrist/standard-white-liberal one) in very classical areas like opera, ballet, symphonic music, etc, but that is just a guess on my part.
This is all assuming you would like a girlfriend/wife who is educated and has her own life/career. If you want a woman who wants to be "taken care of" but who also has a lot of money, you might start looking into the wealthier Christian fundamentalist groups, conservative think tanks, right-wing political funding machines, etc. where you could meet someone's daughter. Those people have more money than God.
If you don't care if she has money, then probably any church would do, except maybe Unitarian Universalist.
3) In the midwest you should be able to locate all of the above kinds of people. Contrary to popular belief we are a very diverse place.
