"Women generally don't find much older men physically/sexually attractive. However, there are a number of reasons why they would be attracted to men who have power and resources."
The assumption that an older man automatically has power and resources is faulty, too. I have been in two relationships with significantly older men and in each case, for a good part of the time we were together they were unemployed. Neither had assets, college degrees, successful careers, or any of the things I had, though I was much younger. Women are told that we are supposed to be attracted to an older man's "resources", yet these days more women than men are going to college, and going on to graduate school. In my relationships, I was always younger but I was the one with the Master's Degree, the successful career, and the resources of my own.
