There's nothing wrong with a corporation profiting. Profit is a very powerful incentive and corporations are very effective legal entities for mass production. The issue arises when corporate executives aren't held accountable. When you have corrupt, greedy, and soulless executives running companies by doing things that are harmful, illegal, or unethical AND they keep getting away with them then that's a big problem. But if you have a system in place with strong institutions and strong legislation that makes sure that worker rights are respected, the markets are competitive, consumers are protected, the environment is protected, and illegal activity is hunted down and prosecuted then there isn't an issue.
