Marinara (with or without meat) is absolutely worth it to make at home; anything out of the jar has almost no tomato flavor. So simple, olive oil, tomato sauce, and whatever seasoning you like that day.
(This is not a blognese recipe, just meat marinara)
It's a checkbox to put on the brochure for idiots who can't make a decision. Also big bonus for the ad-exec when they don't make any changes to the vehicle but still need something "new." Idiotic arms-race for sure. Same thing with how cars are so big now, no one wants to be the "small guy" at the car measuring contest. Because humans are stupid and easily manipulated.
