The underlying issue here is decision making and input. There would be no need to invoke legal rights if both partners could communicate and compromise.
We have the legal right to do a lot of things, such as divorce, but wielding these rights as a threat of sorts results in the erosion of marital trust. Should people be educated about this issue? Yes. But unless these guys are controlling their wives incomes based on Islam (most likely, they’re just controlling) the problem is not Islamic education but rather, marital counseling and maturity. For **both **parties.
