Must a Person have a Job or do Volunteer Work to Contribute to Society in a Positive Way?

I sent my husband an email this afternoon and asked him if I was valuable.

His response: In every non-financial way imaginable!

Isn't that sweet.

But it made me question, why did he consider me unvaluable in a financial way. I do spend the money he makes working at his "job" and this spending does stimulate the economy. He certainly wouldn't buy the clothing and items for our houses that I buy. So, I must be valuable to others in a financial way when I make purchases and pay for services.

My question is must one have a " job" or do volunteer work to contribute to society in a positive way.

Or, Is there another way?
