Nobody would have profited from longer lasting lightbulbs.
In 1000 hours, a 100W lightbulb costs an order of magnitude more electricity than the puchase price. You can easily increase the lifetime of such a bulb to 10k hours, simply be reducing the operation temperature by 20% or so.
Of course, this halves lumens/W, to to get the same brightness, you need 200W of power - which means you pay twice as much over those 10k hours as if you have bought 10 100W bulbs to last that time.
High power lamps, for example in flashlight, used to be specified to operation times below 100h, because this allowed them to almost double the battery runtime...
I'm not sure what's insightful about this post. While it may be true that nobody would have profited in any significant way from longer lasting lightbulbs, obviously the manufacturers would have profited significantly from shorter lasting ones.
