Earlier quoted context omitted.
As an aside, I save ~$1300 a year by bringing in lunch, and ~$550 per year in breakfast, in addition to controlling portions and nutrition. If I had been doing that for the past 10 years I could buy a new car by now, or put a pretty decent chunk into retirement. I now find it absolutely bizarre how many people at work go out for lunch.
It's really good for the economy to go out for lunch. You create a lot of jobs by doing that. If you're mindful of where you eat you can also support immigrant and minority owned businesses.
And if everyone chooses to eat cheap lunch, we could all just work less, and the system would be balanced again ;).
