They should have also used the thin field laminations.
Also, take a look at the stator field. The space between the teeth for the winding wire is quite small. This limited them on the number of strands they could have used for the number of turns.
In other words, with longer stator teeth, more winding strands would have produced much less resistence.

I agree with you about the bearings, laminations, etc, but those are all things that corners were cut on. The wrapping of the stator would help reliability to keep the system running, the rest would just improve efficiency and it is a budget motor after all.
