There are all kinds of hard. And life is a series of choices between which kind of hard you can live with.
Housewives gain a lot by staying home, but they also give some important "intangibles" up. (Plus, taking care of a house people live in all day can be different than taking care of house that sits empty all day.)
I'm certainly not saying you have it easier at all. (In fact, for my personality type, I think your lifestyle would be harder for me. - But that's why I didn't choose it. I have a friend who would hate my lifestyle. And that's why she didn't choose it.)
What I'm saying is that we need to realize that everyone is different, the grass is not always greener, and ultimately, all kinds of families make things work in their own ways.
