That's not all it does, that's just one part of what it does and it only works because we're so rich and prosperous.
If you're a 3rd world laborer you are better off if your masters give you a job at a sweatshop for slightly higher pay than as a yam farmer then channel most of their earnings back into the business to increase productivity so that in 20 years you can afford to send your kids to school and they can become middle class accountants who spend their money on stupid shit they saw on crappy advertisements, as opposed to feudal lords or communist thugs who force you to spend your life on a collective farm.
