"...already we can observe some of these trends in the US and other parts of the globe." 

The USA has full employment, so I can't really see an impending crisis.

"Imagine now, Pick n Pay having to close down because of a massive digital alternative such as MassMart."

You mean more choice, better service and at lower cost? Sounds awesome. The poor would agree with me.

The USA's poorest group of people is the world's 18th richest. I would argue that capitalism is the best system out there.
