No, no it won't. Innovation is generally not accelerated by people that are comfortable/have all of their basic needs met. It's accelerated when you are put into a situation where you need to innovate or fail. Failure is actually the stimuli and it pushes people to succeed more than anything.
If greed is not motivating, then should we not tax the wealthy until they too are in "jeopardy of failure" otherwise capitalism is very far from efficiently deploying the resources of the world.
