However it's not a universal. China has had immense wage growth, and the emergency of a "middle class" income bracket, where no such bracket existed before. Of course it's an economy still in the throws of massive transformation.
Yet regardless, "staring at phone instead of doing job correctly" isn't going to reverse that trend. Or I guess it could for the few unaddicted.
Yea, showing transforming economies to established economies isn't really a great comparison at all. You have two huge things happening at once. A massive transfer of wealth from those 'rich' economies building new factories to use the cheap labor. This drops wages in the rich economies by shipping the jobs out. In the meantime the people in the rich economies have to move to service style jobs away from manufacturing.
In a few decades the same will happen with China as it converts to a service economy.
