I worked in communist china in the mid 70s and worked at three job sites from the far north to far south. Choice was non-existent. For example, you had your choice of any table lamp you wanted as long as you chose Heavenly Bamboo Table Lamp from the People’s Table Lamp Factory #5. It was true everywhere in the country.
I’m sure things are a lot better now.
Of course, when I was a kid in the 50s, you had your choice of Crest or Colgate toothpaste. Now there are 500 variations by Crest and 500 variations by Colgate. Today it’s impossible to walk to the toothpaste aisle and just buy plain old toothpaste.
Ah-hah, you may be of age to notice a brandname that has pretty much gone missing in our lifetimes, at least here in the US & Canada! If you can fill-in this blank, you too may be a bit long in the tooth; "You'll wonder where the yellow went when you brush your teeth with ______" Free market, capitalism and private enterprise does not just introduce products or ideas, for proper functioning, a non-seller must lose shelf space!
Some call it creative destruction but it is why you do not see Pepsodent toothpaste and why you can no longer shop in Fry's Electronics or Radio Shack, and so on! If there is no socialist state manufacturer, the shelf space or store front is not there either!
