Quite the opposite. Dealer has just sold you a car, would have made a decent margin on it particularly being a brand new model with no cash on the hood. Next thing they do, let's squeeze more money out of this moron by telling him he needs paint protection and interior protection. Add an easy grand to our margin on the car. So poor clueless buggers spend a grand or more on what's likely $30 of product, but they feel good about having this "warranty" on their paint. After a few washes that thousand dollar paint protection has been rinsed away. The "warranty" is a complete sham, there's no way a wax is protecting the paint from poor washing/maintenance practices to begin with. And let's say you do mistreat your paint. Pro tip- You can easily cut it back to its original surface condition (ie shiny, swirl/fade free) with even a mild compound down the track. It's not that the paint "fades", it's that crap builds up on the surface. But how do you think their warranty works? They respray your car? LOL. No. Firstly you'll never use the "warranty". But secondly, if some guy ever tries to and manages to indeed jump through the million hoops, all they'll do is give the car a quick buff and send you back to the hole you crawled out of. Sad reality. Same with interior protection. Read the fineprint. It's not a license to damage your seats. If you damage your own seats, they'll tell you to get lost. Hell, I wouldn't want some apprentice spraying some cheap crap all over the interior of my brand new car to begin with.
Conclusion? Paint protection and interior protection is for suckers. But you know what, selling cars ain't an easy business for a dealership operating in such a saturated marketplace. They've gotta make money and if you do sign up for paint/interior protection, you weren't actually ripped off. You just got beat. Same with tint. If you pay more than $250-300 on a sedan, you're a sucker. You do know who generally does dealership tinting, right? A mobile tinter. So you pay the mobile guy's rate, plus the dealership's margin on top of his. Again, dealers have to make money, it's the same way you squeeze every last buck out of clients with your own job.
