It takes much more effort to make a healthy well-rounded meal than just scrambling up “a few eggs”. I’m happy you have enough time, energy, and physical ability to spend an hour making dinner, but a lot of people don’t.
Some have multiple jobs, kids, disabilities, ect. Others live in food deserts where it’s impossible—or at least very difficult—to find cheap, healthy food. Not to mention the people who were never taught how to cook, and would have to spend even more time, energy, (and very possibly wasted food) on learning how.
This is coming from someone who can and does cook cheap, healthy meals all of the time.
