I haven't eaten "fast" "food" in basically forever. It's been decades. Unless 2010-ish Subway counts, and that was only consumed b/c I was driving cross-country and one whole sub was a day's eats that I could stash as-needed.
These prices blow my mind. I can't believe that people are paying so much for so little, and for crappy fried heart-attack and diabetes fare too. I can eat for a day for the price of one of these "burgers" (or "meals" - just because there's more than one item in the bag doesn't make it a "meal" no matter how much the marketers use the term). For the price of a "quarter pounder" here, I can get at least three big cans of "chunky"-style soup, each of which is a meal in itself - all you need is a bowl and a microwave and a spoon and a few minutes to heat. For the price of that burger I can (and do) get 3-4 boxes of cereal at Walmart, each of which will, along with a little milk in a bowl, provide a week's-worth of breakfasts.
Frozen veggies, basics from the Winco bulk aisles, a bit of dairy maybe, a little spice, and maybe a worn, curled recipe book you got from the used bookstore (or not, if you already have the intuition for cooking) and you can eat incredibly cheaply (and well, if you're careful) in the US. No need to fill your body with expensive McShit just because the ads tell you to and justify your doing it. Everything changes if you're already homeless of course, that's gonna cost you, but just be aware that McEating is going to get you to that state of being all the sooner.
I think that people eating all this McShit and justifying it as some kind of necessity ("too busy shop and cook!") are just addicted to sugar/fat/salt/industrial-chemicals and who demand "treats" of such things each and every goddamn day (vs maybe once every few weeks 40 yrs ago) because that's what they "deserve". I understand, a treat is all you can aspire to, you're never going to buy a house or have a decent job, but blowing what little $ you have on ruining your health and mobility and sanity doesn't seem to me like it's going to help get more out of life. No more than a daily 12-pack of McBeer would, and for that you wouldn't have to wait in line.
