I think that is an old-fashioned, 1950's kind of idea. I keep a separate account that my work money goes into, and when I want something I don't think my husband would approve of, a new piece of jewelry, or a nice decoration for the house, I like not having to ask permission to buy it. OF course, my husband is cheap, and lets me know he thinks not spending money is always the correct choice, no matter how tempting the new thing is. So for me this account is a necessity. I just come home and say, "I bought it with my money." On the other hand, I don't offer to pay taxes out of my money. So we both know that the amount I keep for myself is inflated, since his income has to cover the tax. But my husband makes a lot more than I do, so he doesn't try to make me see how pitifully small my income is.
