The only reason for a manufacturer to want to produce a cheap car is to sell a ton of them at a low margin. If not enough people are buying them, then there's no reason to continue selling them. At sub-$20,000, you're going to be better off buying a used car than a new, bare bones car. This wasn't the case decades ago when cars were a lot less reliable and generational improvements were much larger.

>when they have a $7000 sales incentive on that monster vehicle that is not a sign that people want to buy a monster vehicle

What cars are you talking about? It's generally the "monster vehicles" that have the greatest markup (e.g. Bronco Raptor)
