Not really. Think about it for a moment: are there more people actively searching for better solutions to each and every single problem they may or may not know they have? Or are there more people like you and me who go about their day just fine completely oblivious that there might be out there a far better way of doing things, or not even bothering to spend a second to address some nuisance they have?

Yes, it would be a world where fortunes were spent on R&D whose outcome benefitted no one at all because no one ever heard about the outcome.

Also, as a corollary to your anti-marketing stance, multiple redundant R&D projects would be wasting resources developing stuff that was already developed and reinventing the wheel primarily because no one knew that it was already done.
