That's interesting. I know a lot of old cookbooks really stress eating economically and using leftovers.
The concept of "Home making" in the 1920s-60s was based on a single-income family, and not surprisingly features lots of ways to save money. Its very illustrative to read today, when many families are having to cope with the same situation and not fairing very well at it. I know from experience that you can raise a family well, if frugally, on a single income if you're very careful with how you spend your money.
