Quite a few authors have pointed out that the "financialization" of American businesses, with a focus less on innovation or investing in their workforce and more on massaging their numbers to meet shareholder expectations, has created a lot of short-term enrichment for the super-wealthy while absolutely destroying the middle class as we know it. This seems like more fuel for that fire.
Really, anyone with a 401k or similar investments has benefited from this. That's a lot of middle class folks. Your parents, your grandparents, and very likely you. It's far from limited to the super-wealthy.
So, we will see if this privatization of pensions really benefits us all or merely enriched a generation of asset managers while absolving the corporate and the government from providing pensions for workers.
