I would want my would-be husband to have equivalent to higher package than mine. There is one simple reason behind it, every man would have more or less amount of male-ego (please pardon if i offend someone, but believe me thats true). I earn enough to pay my bills, go on touring, and also can take responsibility of family. so its not the case that i have greed of having his hefty salary. Its just i dont want his ego to get hurt when he earns lesser than me. and it really matters in personal life.
So its better to have husband who is earning equivalent or higher than that of wife.
