nbyet, good sentiment, but IME, if you don't blame the culture, you blame the man. You blame the man, that's it. Game Over.
I dropped my misogynistic, abusive 'H' off at the airport last Thursday. I never thought life could be worse than the 3 yrs I spent in his country, the abuse, the mind games, the violence... but I was wrong. The days before he left rank among the hardest I have ever lived. The 60 minutes in the car to the airport was an A-Z of all the manipulative tricks in the book.
For years (while in Egypt) I blamed the culture for much of the problems we were having. I felt sure that when he got back here (We met here, he'd lived 20 yrs in London before we left) I though he would re-learn everything he was before.
I was wrong.
It's OK to be scathing about a country that doesn't meet your basic needs. Egypt - for me - was hell on earth, I couldn't accept a single part of it, the way children/women live, are treated, the men, the women, hygiene, respect for life both animal and human, you name it, I couldn't accept it.
It's OPs opinion, she may be wrong, she may be right, she is talking about her experiences and what she has observed and can or can not accept.
I know there are many people that love living in Egypt, I just have no idea how, but they do 
I've had this discussion before, when a H is forrin, we find it harder to pick up subtle nuances, and make allowances way more than we would for a bloke from our own culture. The language issue hides a lot, we think Oh he didn't really mean to say it like that, or if you challenge them, often (Mine did anyway) they say, oh you got the wrong impression, it's cos I don't speak english as a first language. 
TBH OP, there is a conversation that needs to be had. That as a wife here in the UK, married to him for as long as you have been, he ought to have cottoned onto what's what by now.
Then tell him that THIS is what you expect/need/want from a partner and also what YOU are prepared to GIVE.
You need to negotiate a compromise, an agreed percentage for savings to be sent, savings to be kept for your OWN rainy days. Or if he would like to send more money, then he needs to get a 2nd job.
If you going back to work is what you want and if it would put your family in a much better position then that is logically what you have to do. If he is not happy with that arrangement, he needs to get more jobs to compensate quite frankly.
You need to stand your ground really.
