corporations thriving is bad for the economy
Profits in a perfect competition would be 0, or near it, since no company could charge more than what a product costs to make without being undercut by another company. That would be best for the economy.
High revenue, low profits.
Corporations thriving = more jobs
High demand for services from a corporation, and the corporation required to hire to meet that demand == more jobs. High profits is just money going into stockholders bank accounts, meaningless to anyone but those already with money.
If the corporations are doing well, then America does well
All depends on how you measure "well".
