From what my friends in China tell me this is changing in a big way, mass produced foods are taking over for the labor in even small and unlicensed vendors. They're hitting some sort of economic threshold that we have in the USA where it's just cheaper for every diner to buy frozen from GFS than do it themselves.
It is indeed changing in countries like China for a variety of reasons.
Some of it being the pressure and pace of modern life. Some of it being western foods being perceived as a "luxury" item and status symbol (e.g. Starbucks). Some of it being changes in economics.
