>>Exactly. The food stores should only have one kind of bread, milk, butter, cheese and so on. And everything should be made in big factories owned by the authorities, where all the workers had the same salary. And only one model of all kind of clothes as well, in one color, blue. Hmmm. Reminds me of China not so many years ago.

>Just watch any movie from 70s, 80s, 90s with a good scene of a fight in a supermarket, like, say, FX. Stop the frame once per shelf, then count the items you can't buy anymore. May be more interesting than the movie itself.

Specific brands come and go all the time, but in fact there has been an explosion in the number of grocery items available. This is especially true in the produce aisle, where you can routinely find fruits and vegetables that used to be available only in specialty stores, if at all. Or the frozen aisle, which is now two or three aisles in a typical good sized supermarket. In fact the most striking thing to me about movie scenes in supermarkets is how small they were compared to today. That is surely not a sign of all the brands being killed off.
