Do you HAVE to work?

I am surprised by the amount of people who like to question my family's financial status by the question "do you HAVE to work"? At times I am appalled. Other times I'm surprised. We live in a world where two incomes is the normality not the rarity. That is why I am surprised to hear these questions being asked of me.
Maybe people feel like it is no big deal to ask if I really have to work. Yet, for me I wonder what do they really mean? Do they mean: "hey are you just killing time working on your career before you have kids and drop it all?" Or do they mean: "hey, why should you work, clearly your husband works, is that not enough money for you two?", or is it possible that they are saying: "common, everyone knows that your work is silly, why don't you just give up and be a stay at home wife!?"
Well in any way that it is meant, I am totally shocked an appalled. Firstly, if I haven't told you otherwise, my household income is none of your business. Secondly, I, like you have obligations and clearly those include me working! Thirdly, why are you sticking your nose into my business!!! If I have shared with you that I am currently unemployed and looking for a job, then what I am sharing with you is that if you can help me out that would be great! If you can't, then hey know that we are available for Shabbat meals!
Its not that I am wishing hate upon people that are interested in helping me out, I'm just shocked an appalled at the level of intimacy that people are willing to go into. Of course I cannot respond with none of your business. Or, are you kidding me, are you really asking me this! I usually respond in a clear, level headed way "We are great till the unemployment runs out, then not so much". My husband on the other hand had a great idea, "why don't you just tell people that you wouldn't need to work if they would like to pick up the tab for our mortgage". Even though I do agree with him, I still think it's kind of rude to answer this way, though these people have no mind about how rude they are in digging into my life.
I am in shock that this is even a question in our day in age where most women I know work. Some work because they have to. Some work because they want to participate in the family finance and want some extra cash to kick in. Some work because of the combination of those two reasons. I am sure there are many, many more reasons why women and men for that matter work. Yet, I do not think that it is anyone's business which of these reasons is true for me!
