Most people don't even want a diesel vehicle due to fuel cost and the fact they prefer a standard gasoline engine.

Unfortunately, you're correct. Most people are indeed ignorant and unable to do math.

My non-diesel gets about 32mpg on the highway, if I lay off the turbo.

Lets see. My diesel got 45 mpg on the highway.
Fuel is at most 30% more expensive although right now it’s almost the same (here the price generally 2.19 for reg or diesel).
AND the engine is good for 200k.
