Are they entirely to blame? No. Everyone who capitalizes on the deal shares some blame. The consumer and the economy do get hurt. Late stage capitalism is starting to destroy what was good about capitalism and we need regulations to keep things sane.

There is a finite amount of capital in the world (with a little more printed each year of course). But they're not printing 20% more every year, so companies can't keep expecting to grow by 20% every year forever. It's just not possible and once a company reaches certain thresholds, we need regulations that prevent them from destroying the good parts of capitalism for simply more money than they had last year.
