No, not rich guys (at least not exclusively), we are talking about men you are acceptable to those picky women.
Apparently, the best strategy for women for finding a marriage-able partner is to do it scientifically, go through dozens and dozens of men, and make the choice semi-scientifically.
My opinion on this is that it will not likely work for most women. This assumes that of the men that these women date, they have their pick of the best ones. But I get the feeling that the women doing this are not bringing a lot to the table themselves.
