I think we're missing the forest for the trees here. it's not about cooking, it's about making sure your whole life isn't "ready-made meals". Put the metaphor into every other aspect of life.
We will all take shortcuts somewhere, but shortcuts imply a destination. if your destination is just more McDonalds, I think we are missing something vital to out lives.
>a meal cooked by somebody else always tastes better than when you cook it yourself.
the "joke" implied intimacy in said meal. It's not the meal, it's who made it for you. coporate billionaire food chain pumping out "burgers" cooked by minimum wage workers with no upward mobility is about as distant as you can get.
