What is the meaning behind the painting Decalcomania by Rene Magritte?

I think the meaning is:

our window on the world is capitalism (right half of painting) - business shapes the way the world looks, its streets, shops, opportunities and desires. And it's inescapable. If you look outside the world of capitalism (left side of painting), your focus is drawn to the central figure - the motivations of men (and woman) in pursuit of advantage and opportunity.

Not sure how accurate this is but I find it satisfying.
