I don't know if there are any credible statistics on injuries/deaths from rewirable-plugs-wired-with-live-and-neutral-transposed, but if there are I suspect the number is distinctly noise-level when compared to the total number of plugs in service.
IMHO the move to appliances coming with fitted-plugs/pre-assembled IEC-leads was the biggest safety-related 'thing' in the last 30 years. It's a move that's welcomed by consumers too - so much morte convenient - no more buying an appliance and getting it home all hoping to enjoy it then finding there's no plug.... (so you stuff the wires into a socket and 'assist' the connection using a couple of matchsticks and a teaspoon).
Moulded-on plugs probably work out cheaper than separately-wired ones: another win for everyone!

Practically everything sold in the US had some form of molded plug attached to the power cord(mains lead) since the mid 30's. It was a cost saving effort and the NEMA plug configuration was well established for at least 10 years.
