You can innovate all you want, but if people don't want or need it they aren't going to buy it. Moving from a farming/subsistence economy where most people had something to do with food production to survive, to our present post-farming/industrial whatever-this-age-is was a huge leap, and there was a lot of peripheral infrastructure to build up. Now we're there, and yes there's more room for innovation, but there's no existential leap forward in front of us. We have enough. We're not fundamentally changing the way of the world (not in developed countries). That doesn't generate a lot of peripheral work.
