What is your opinion on stay at home wives?

Times have changed and I’ve noticed a lot more women are leaving their chores behind them to go find a job for themselves. Personally I don’t see anything wrong with being a stay at home wife/mom as long as the husband can financially support the family on his income. But what is your opinion? Do you look down on women who stay home while their husband works all day? Or is it still acceptable in today’s modern society?
