You're supposed to have an easier time controlling your car in reverse. At least in all cars I drove, including my father utility truck with only side mirrors (and tbh, the small convex mirror below the regular one should be present on every vehicle).

When the parking spots are parallel to the road, I see people back in all the time, so I know it should be true for everyone.

Easier is relative :) You have better maneuverability in a way, but it's harder too because you're looking the wrong way, and the steering wheel turns opposite way to that which you are used to. I always have to think to myself "left hand down means the back goes over there...", it's not as instinctive as driving forwards.
