Gardening to save money?

I spent an hour gathering these beans this morning. I'll probably spend another half an hour processing them. I could buy the same amount for about $5, which makes my hourly rate pretty dismal.

Now granted, these are tastier then what I get in the store, and probably healthier as well since these will be more fresh when they are eaten. (Most of them will be frozen and eaten this winter, but even then, I am guessing freezing them right away preserves more nutrition then what probably happens to commercially processed ones.)  They were not harvested by children or people being exploited. And it is quite satisfying to eat food you have grown yourself.

But if you are in it for the money, I'd just get a part-time job
