I guess I should have clarified that I meant there was no inherent ceiling on the size of the economy (other than the amount of mass and energy in the known Universe, although I hope we'll figure out something else to do before we consume all that), but yes, the growth rate in any given year is limited by resources available and human innovation. Sorry for the ambiguity. I guess my point is that the reason high percentage growth is easy for small companies is because they can rapidly expand to fill an existing market that is much bigger than the company. The reason it is hard for big companies is because of market saturation. The economy as a whole doesn't work that way. It just relentlessly grows with our ability to acquire resources and never-ending human desires.
