" I dont know (or maybe i dont understand) what is your question, but i can tell you math is not the answer.

And even if *some* men (muslims and not muslims) dont agree with women reaching education services, islam encourages everyone to learn and seek knowledge; up to what level, is a personal matter.

Is true (in my opinion) that in poligamy, one wife gives 100% dedication to her housband, while the housband gives half dedication if he has two wives, or a quarter if he has 4 , BUT these marriages need first to meet some rules and regulations + none is forced (or better say none should be forced) in such marriage, so if a woman agrees and she is happy i dont see what are the other peoples problems, sure we have more important things to ponder on.

And Allah knows best."
