Societies show variable acceptance of polygamy as a cultural ideal and practice. According to the Ethnographic Atlas , of 1,231 societies noted, 186 were monogamous; 453 had occasional polygyny; 588 had more frequent polygyny; and 4 had polyandry.  However, as Miriam Zeitzen writes, social tolerance for polygamy is different from the practice of polygamy, since it requires wealth to establish multiple households for multiple wives. The actual practice of polygamy in a tolerant society may actually be low, with the majority of aspirant polygamists practicing monogamous marriage. Tracking the occurrence of polygamy is further complicated in jurisdictions where it has been banned, but continues to be practiced ( de facto polygamy ). 
A smart woman knows that her future husband cannot just rely on the lottery for their meal for the next month, she knows that her partner should be able to give her and her family financial security because he has a plan. Where would he want to work five years from now? Does he plan to buy a home? Does he want to upgrade his car? Does he want to go on a big vacation next year? The man’s financial plans may be long-term or short-term, what matters is that he has a financial plan. The plan need not be as detailed as an accountant’s asset and liability sheet, what you need to feel is that this man you are about to marry has plans on where he would want to spend his money. First, he needs to have that money to spend, and secondly, he needs to have a clear direction where he wants to spend his money.
3. Love is far from "all you need." You need mutual respect, shared goals and compatibility way more than you need love to have a sustainable, lasting relationship. People "fall in love with love" just as Kim Kardashian showed us, because they think it will carry them the distance. We all want to be wanted and we love to love yet, if you had a recipe for a strong, healthy relationship, it might look like this: 3 Cups respect; 2 Cups shared goals; 2 Cups compatibility, 1 Tablespoon love, 1 teaspoon attraction (optional!). (Of course a relationship has many more ingredients than this but you get the idea).
