Being feminine is an occupation. Women know that feminity is exactly what attracts men and maintains attraction. The reason women are feminine is so that they can be supported by a man, or in order to fuck a man.

A women who spends all her time earning income has no reason to be feminine. Her job of support is already accomplished.

So women working has a downside.

And this is again why I consider the best arrangement is for your woman not to have any job. Forget about whatever income she can bring in. That is insignificant in comparison for the value of her doting on you, and relying on you.
