A lens that is affordable and is in plentiful supply, like the Volkswagen was the people's car, the model T Ford etc.

Historically: The Cooke Triplet or even simpler (e.g. achromat or even meniscus). Tessars were premium products and Planars (double Gaussians) for most people unaffordable.
Today it must be the simple lens in a mobile phone. Even a simple 18-55 std-zoom is quite a specialist item I think.
