Right, but imagine that with cars not TVs. To show the cost change of a car from 2000 to 2020 I wouldn't show the cost of a 2000-quality car in 2020. I'd show the actual median cost of a car in 2020.
It's more complicated for cars, because you often can't get a 2000s-quality car even if you want to. There just aren't any cars on the market today with the size and (lack of) features my current car has; whenever I need a new one, I'll have to either buy another ancient car from the 2000s or pay more for extra features and dimensions I don't need.
With TVs, though, Best Buy sells 2000s-quality TVs for like 60 bucks. I don't think it makes sense to say that TVs haven't really decreased in price just because most people would prefer to buy the fancier ones.
They still make small and normal sized cars (for now), they just aren't as popular anymore.
I just did a check of the msrp for a cheaper Toyota Corolla near San Francisco and it's MSRP is almost exactly the same as the base 2000 Corolla when adjusted for inflation.
