I don't really agree with the original premise, but I would point out that:

the problem is that there is no product differentiation when it comes to road usage. You're either on it and paying the same fee, or you're not.

It's not like food, clothes, housing where you might be paying a lot for these things, or you might be paying less. We price specific items of food without regard to income, but there's a wide variety of items of food to choose from, at different price levels.

Not so with a lot of transportation.
