In the US, consumers like stuff that is cheap, and don't seem to care much if it is poor quality and breaks - they'll just buy another.
In the UK, at least when I lived there 30 years ago, people seemed content to pay more for quality items that would last longer.
I noticed when I moved to the US and saw same brand, e.g. Black & Decker selling cheap plastic US-only versions of products compared to their heavy duty cast iron counterparts sold in the UK that would last forever.
The gist is that by running bulbs at a lower power, you can greatly prolong its life, but the downside is that it doesn't heat up as much, and since emissions spectrum correllates with temperature, ends up being much worse at converting electricity to light, which ends up being not worth it.
"The cartel tested their bulbs and fined manufacturers for bulbs that lasted more than 1,000 hours."
Make a million light bulbs and sell all of them and then do whatever it is that you want.
Similar to finding a cure for cancer. There's a huge market that you can just eliminate and then retire.
Some decades ago, a manufacturer from East Germany, former GDR, was participating at a fair for lights and light bulbs. This manufacturer invented a light bulb that never burns its glow wire.
At some point during the fair the companies from West Germany had a big laugh on that manufacturer, mocking him and his invention. Their argument: If you build a bulb like this, how are you going to make money?
Now, I cannot say why we don't have glasses like this already but my assumption is that the monetary incentive is seen as being contradictory to such an invention.
