My feeling of the subject is similar to the food marketplace.
You can have a sublime meal at your local family run restaurant. Fresh ingredients, exquisite experience, fine wine. Maybe that restaurant makes a profit some years. Maybe some years it doesn't. Sometimes the meals can be a bit pricey. But the food is more often than not lovely, hand crafted by a chef, lovingly prepared .
Or you can have a McDonalds. A mass marketed product enjoyed across the world for the everything now consumer. That makes the company $6Billion profit every year.
Sometimes you have a blow out and go for the 2nd option. But if you choose that option every single time, something's got to give.
I'm with you on the quality cooked meal over a Muck Donalds but yet again it is subjective.
I'm sure eating in that exquiste restaurant would cost a small fortune after a while so it is a treat you have every now and then.
The other thing is why is Mucky Ds so popular?
The mass appeal of a slab of meat in a bun with some lettuce and ketchup accompanied by some anorexic chips (fries to you Americans).
It's basic but people seem to love them.
A bit like a blockbuster movie.
Now the exquiste meal is not as popular but appreciated by the more discerning epicurist.
A bit like a Fellini film.

Different tastes appeal to different people.
You have got to admit though those top chefs do tend to look down their nose at the fast food outlets as if they are better than them while the FFOs just have to point to their popularity and their profits.
