Yeah bad analogy.
Most vendors sell snake oil.
Most colleges don't.
What exactly do you think a vendor can do for you? Nobody can teach you how to trade. Do you think they are going to reveal some holy grail that for $50 or $250 will allow you to mint free money the rest of your life? Do you honestly believe trading works that way? Some of the most highly lauded individuals in academia from the University of Chicago have been responsible for losing billions in massive hedge fund blow ups. Most finance professors couldn't rub two nickels together in the real world. But you are down with paying them 150k for a piece of paper? But wait, $250 to see how some guy trades FX and you call that a scam? Come on. I could care less for most vendors. They are selling a low quality product at dirt cheap prices. No course is going to make you into a profitable trader. However, most of these shitty product offerings do offer one thing. They plant seeds. They get you thinking about things. Even if it that thinking is how NOT to trade.
