If you hire a lot of people and then steal their wages you don't go to prison either. You can be proven to be a murderer (OJ Simpson) or a child rapist (DuPont, https://www.forbes.com/sites/denizcam/2019/06/14/how-a-du-po...) and you won't get punished if you're wealthy enough. If you are poor, you'll get life sentence for stealing socks. It's not a bug in US judiciary system, it's how the system was designed.
