I didn't either until I talked to a mortgage agent a few weeks ago. She pointed out that the amount is not insignificant for families with lower incomes and they know that anything that reduces CCB will basically reduce risk (because higher income), so they count it. At a macro level though, this is terrible for housing. All it will do is give families more room to bid up prices.
Don't need any of that. There are already caterers that provide various school lunch services of various kinds. School kitchens like France are actually rather inefficient. Much easier to have larger industrial kitchens and simply deliver food carts to each school. There's a good video from a Canadian who lives in Japan explaining how school lunches work for kids there. It's a high quality, low cost, plant forward, seasonal menu, served family style in class by students, to each other. And it's made in school or centralized kitchens (location dependent) daily. Highly recommend watching this:
Example of a centralized Japanese school lunch kitchen servicing a whole bunch of schools:
Here's an Indian kitchen that feeds 75 000 kids per day:
And this is an example of a Korean megakitchen that produces 10 000 meals for office workers at 7000 won (about CA$7) each:
Japan and Korea are not low wage, low cost countries. What they have in common is that they industrialize the process, focus on seasonal ingredients and limit expensive proteins like meat and cheese. What they produce is not only cheaper, but healthier and tastier. These kitchens also creates high quality employment for cooks and chefs normally working in hard-driven restaurant environments.
