You said it yourself perfectly...

"are you going to spend extra money for components which may increase the life to 7000 hours if it raises the price perspective too high?"

The key word in that sentence is "price".

Price is the AGREED amount of exchange between the consumer and the producer.

So in other words, you're saying designers/producers are not willing to make products that the customers won't agree to buy...

Well, Duh!

If customers won't want it ("price" is too high), then why exactly should producers make it?

The whole point of "markets" and "prices" is to align our productive effort with our needs and wants. Spending productive effort on something we don't want (apparently what your calling for) is wasteful.
