Find the reason why your wife doesn't want to work and try to have an open conversation. For example, maybe she's too tired from carrying for the house and kids if they're too young. Perhaps she's struggling with low self-confidence after not working for a while. If there's no valid reason she can overcome with your help, she's probably selfish and plans on you to satisfy her financial need. Money is a sensitive subject and should be approached calmly and reasonably.
