It is a very cult-like statement. One could imagine it being said to a young person raised in a commune in the backwoods of Utah or an ultra strict Amish community. It can only work on people who know nothing of the World bar what their elders have told them .
Of course The World has it's dangers but it offers rewards too, if one uses a modicum of common sense.
What has The World ever done for people?
Well: education, a higher income and standard of living, social friends , romance, marriage, children , grand children.. a whole lot of fun!
Apart from those things.....NOTHING !
