you might do well to read up on a little history, say of the "Great Leap Forward" in the 1950's. Apparently, by your thinking, eating out was unthinkable back then, scarcely fifty years ago, because Chinese were eating grass and twigs, and the occasional afterbirth, to stay alive thanks to the policies of the Great Helmsman.
*Update*
There is NO threat of famine in China. Period. Ever again.
