I fully expect Jeremy Clarkson to have never baked a loaf of bread in his life.
I'll occasionally bake a loaf of bread, here in my home kitchen. I can't do it with only wheat flour, I need water, salt, sugar and oil as well. So I have to pay my municipal waterworks, a salt miner, a sugar beet farmer, a rapeseed farmer, a wheat farmer, and whatever you call a yeast maker, plus their adjacent industries (I don't by sugar beets, I buy refined granular sugar, etc) and multiple truck and train drivers who move all of those goods in their various states of manufacture around the continent.
Then I've got to bake it, I have an electric oven so now the local energy concern gets their cut. It's that, or get a gas oven and cook with natural gas (fossil fuel methane), or misuse my backyard grill and cook with fossil fuel propane, or get out my axe, fell a tree and build a fire, which is labor intensive on my part.
Sometimes, watching Jeremy's Farm, there's an amount of "I didn't think it would take this much knowledge or skill." Because jackasses like me with 40 square feet of vegetable garden and some packets of seeds from the home center manage to make food. How hard can it be to scale that up to hundreds of acres? Modern farmers need a bachelor's degree, you need to know about plants and animals and soil and all manner of shit to be a farmer. "Put seeds in ground, plants grow." Yes, but actually no.
Sometimes it's "He's still The Orangutan from Top Gear." He buys a tractor that's way too big and then struggles to drive it, lol.
A lot of times it's "I don't think rich TV man actually understands how society works, people have just done shit for him his entire life."
