Why would you go to college to get a business degree taught by a professor that doesn't own a business?

Why would you go to college to get a business degree taught by a professor that doesn't own a business? That seems like the biggest scam in US history. And mind you, you don't have to have a degree to become a business owner and you don't have to have a degree to become an entrepreneur, but you have to have a degree to work for one. You have to have a degree to work for someone else and build their dream instead of your own. But you don't have to have a degree to own your own business. That should make you question everything right there because why are you paying $100,000 to go to college to get taught how to run a business by a professor who's never ran a business? That doesn't make any sense to me in any way shape or form. I literally don't know how to wrap my head around the fact that people actually do this. People DM me all the time, they're like, should I go to college to get a business degree? No. Find a successful business owner and have them mentor you. It's like a tenth of the cost and you're actually going to learn from someone who actually did it. But no one wants to talk about that scam. Because why are you going to college to learn from someone who's never done it? And then also, you don't have to have a degree to own your own business. Because you know what it requires to have a business? Not a piece of paper saying, oh my god, I graduated. No, it takes hard work. It takes passion. It takes grinding your ass off. It takes will. Like it takes everything out of you, but then when you make it, you make it and you realize it was amazing. It was everything you ever wanted. That's what you realize. But you don't need a degree to do that at all. And that should make you question the whole concept of college in itself.
