Let us analyse THE SO CALLED SUBSIDY IN LAY MANS TERMS.
Your family is blessed with fields upon fields of yam, tomatoes, onions etc that grow naturally in the wild by themselves (that is the Oil) on your land. Your wife has set up a restaurant selling a nice plate of pounded yam for N1000 (international price), it costs her N100 to gather (explore and get the Oil) the food items from the farm, and N100 to cook (refine ) the food. She also sells the raw food (crude Oil sales) for N700 to others (they refine it at N100 to sell at N1000 also).
Now your greedy wife has been selling you her husband at N600 per plate, arguing that she is subsidising a plate by N400 because she loves you, she is even arguing that she is selling below the selling price of raw food which is N700, she argues that what ever way you look at it she is losing money, and this cannot be sustained.
Your wifes kitchen caught fire, so the cooking has stopped, she now buys food from those that cook it, that she supplies the raw materials at N700, they cook it for N100, and sell it back to her at N900 per plate. She is telling you that she now has to subsidize your food by N300, since you are still buying at N600. All she needs to do is repair her kitchen (refineries) or employ others to cook (prIvate refineries) and she could be able to sell you food at N300 and even make profit.
Solution: THROW HER OUT SHE IS A BAD WIFE, A THIEF, LONG THROAT ETC.
Pack all her belongings out, her stay is over.
the option is for you to call her back to her senses and if she refuses you send her packing and look for another person who will not be greedy as her.
She is an ole,barawo,lifter.This does not fit a wife o.Send her out of your life,out of your house and out of area.She is a life destroyer.
