because most of the world has no middle class.

I agree that some middle class jobs seem to be being offshored or automated, but there are middle classes all over the place. Look at the change in, say, Malaysia in the last 40 years. The hordes of people shopping in the malls in Kuala Lumpur and jamming the roads solid with their cars aren't all 'elite'. They're journalists and teachers and business people, and their parents or grandparents were clerks or labourers.
Look at Africa: with more education, more medical care, more radios and newspapers, more factories, there are more teachers and medics and engineers. I know a bloke who grew up in essentially a peasant village, working the land. He was bright and he got himself an education and he's now a bigwig civil servant. He's very middle class.
People, we are totally off-topic.
