> Now women have to work just to be able to afford a house on two incomes which previously cost only one.
I frequently see people argue that you now have to have two incomes to have a normal middle-class lifestyle, but it doesn't square at all with my own experience. I come from a pretty conservative sub-culture, where it's much more common for a husband/father in a family to be the primary breadwinner and for the wife/mother not to work. Sure, a lot of our friends are highly-paid engineers and the like, which makes that easier. But others aren't - off the top of my head, I can name teachers (in a state known for terrible teacher pay), law enforcement officers, city maintenance workers, etc. All of these people are figuring out how to live a fairly normal middle-class lifestyle on one income.
How is that possible? We make other choices that support the goal of a single-income family. Most of us shop at Aldi, not Whole Foods. Nobody drives new cars (our nicer car is a 2005, for example). We do a lot of home maintenance ourselves. We share clothes, toys, and kids' supplies with each other, or get them on consignment. You get the idea. (Oh, and we also don't have to pay higher-tax-bracket taxes on the second income, high property taxes on big homes and new cars, or pay for daycare when we're at work.)
There's of course nothing wrong with women working or with nice cars or shopping at Whole Foods, and I respect the fact that different people choose to handle these issues differently. But don't be deceived - it's still possible for most middle-class Americans to live on one income, as long as they're willing to choose to make the sacrifices in other areas that facilitate that lifestyle.
(I won't claim to be able to speak to how this goes for poorer classes.)
