I think you're also discounting that Amazon probably paid him several million dollars to film that show and he also made a lot of stupid and poor decisions for the purpose of entertainment. So while a lot of his struggles are real his actual revenue number is completely unreliable. Also most farms don't start off by buying a several hundred thousand pound Lamborghini tractor and getting all of their equipment every year.

That's sad the show is great entertaining and informative so totally watch it
