The old sealed beams were a cheap, crude light. I agree that today's
lights have the issue of the plastic lenses wearing, but they have
huge advantages over the old sealed beams too.

Indeed, if they hadn't thrown away the good part along with the
improvements, it would be _agoodthing_(tm)

There's no really good reason to have to put up with the shoddy plastic
other than it's simpler and cheaper for the manufacturer. They also
probably don't worry about longevity too much in their design decision
process for such--consider it either a consumable or that the original
owner won't keep the vehicle long enough to notice combined with the
fact that the largest majority by far don't have such climate and road
conditions as do here for rural use so don't really care as it would be
designing to more nearly the extreme instead of the mass market.
