Look around the animal Kingdom. What you will find is with most animal species it is the male that is naturally, thru selection, more physically attractive. This is somewhat subjective, but generally considered to be the case.
We humans, animals that we are, can be argued are likewise. At least naturally. Both genders do all sorts of things such as shaving, make up, augmentation, working out, ect... that attempt to improve our looks, but naturally, as with most animal species, if unbiased by gender attraction it is the male again.
So how does that apply to MM you wonder.
In the US about one in 10 households have a net woth of 1 million or more. By far most those households are lead by a male member, over 55, and married. All that said, think of the likelyhood of finding a single attractive male with a net worth over a million. Do some math, and understand there are far more attractive women than millionaire single men. Think how in demand an attractive, younger, millionaire male is.
Good luck in your search.
