Are Online Business Courses a Scam?

I believe that the way most people think about buying online business courses and coaching is fundamentally flawed. You wouldn't pay for coaching in kickboxing, work with the trainer for a few months, and instantly expect yourself to be competing in the UFC. You would understand that you also need talent, work ethic, and a long duration of commitment to reach the highest level. It's the same with business. People buy 1 course or mentorship and quickly say it is a "scam" cause they didn't make money. The truth is you have to collect a wide range of "classes" and experiences, stick with it a long time, and then eventually you might achieve success.
