"Economic growth is the new things we do."

"Perhaps we should get really basic here. Economic growth is the new things we do. Can be doing old things in a newer and more efficient manner which frees up resources to then do other things as well. Can be doing something entirely new. But growth simply is those new and additional things.
    "The rate of growth is therefore the speed at which we do those new things....
    "A planning system which triples the time necessary to do something new therefore slows economic growth."
