Cooking isn't hard and these days its laughably easy to learn how to cook. I have a sneaky suspicion that people also know that a takeaway isn't cheaper than cooking at home but when they say that, someone says "oh poor you, you need help, its someone elses fault you are in this situation, bad government".
The same people who can figure out everything they want to do on their phone, the same people who can somehow manage to order stuff online, buy a car, tax and insure a car, get a new phone and contract. Those people can't cook because no one taught them? Do me a lemon. I was never taught to cook by my parents. I'm not a complete idiot though so I taught myself and by taught myself, I got cook books, watched videos, engaged 2% of my brain to think "how would I cook pasta and a sauce when I have dried pasta with instructions on the pack and a jar of sauce with instructions on the jar".
Its simply easier to eat unhealthily and order loads of takeaways. Its as simple as that. In the same way its easier to sit on the sofa every day instead of doing some exercise. People are lazy and the carrot doesn't work. People need the stick. They need to be treated like children and have their nice things taken away from them when they misbehave.
Sorry for the rant but people claiming they can't eat properly because of poverty or ignorance when they buy takeaway is one of my all time biggest bugbears.
