We both lost cafeteria breakfast/lunch when we got new jobs after moving.
Making dinner used to be really easy, just grab some fresh ingredients on the way home and throw together something small and healthy.
Now it's a whole performance. We're constantly trying to make bulk meals, and store the rest for breakfast/lunch. We've gone from preparing 2 servings of food per day to 6 or more. We needed to buy larger kitchen appliances and equipment just to cook/store it all. There are 3x more groceries (We shop on foot and bought one of those little carts) and 3x more dishes. It doesn't seem like much but I've lost at least 30 mins a day, but probably a lot more on average. The food I am eating is, on average, less healthy, less diverse, and less tasty (I am no professional chef).
This article just seemed to resolve to a point that free lunch was a corporate tool to discourage "family formation", and I ultimately disagree. I think a lot of working parents would love to not have to worry about preparing their own lunch meal on top of their families.
I just don't see the connection of "free food == single life", and the article doesn't really establish one. At worst I'd still end up with the same amount of time, and at best it has given me more free time to spend with my family.
