China hasn't got free speech either. What is your point?
As at last check China was on track to be the #2 economy in the world and perhaps the #1 economy (replacing the US). If you wrote the article title "All the top economies of the world don't have mandatory vacation" its a much different message is it not?
One headline seems to advocate that the US is barbaric for not allowing vacation, and the other headline seems to advocate that you can't become a top economy by giving away GDP.
I agree with you that its people do not benefit equally from its economy but I don't tie that into 'developed' or 'not developed'.
