"The popularity of amateur photography has made distorted photos made with cheap cameras so familiar that many people do not immediately realise the distortion. " The distortion of cheap cameras, has nothing to do with perspective distortion.
Barrel distortion may make the top of a building look smaller but another cheap lens could have pin cushion distortion which is the opposite. If a photo is taken with the camera pointing up at a tall building with a lens with pin cushion distortion this would actually correct the distortion more than an expensive camera.
