There is nothing American about it. Global sum of all GDP&#x27;s has grown for all recorded history. Even if inflation adjusted.<p>If you mean that GPD can&#x27;t grow &quot;infinitely&quot; as infinitely high value, then I agree. If you claim it can&#x27;t grow for infinitely long time, well at some point sun is going to swallow earth or heath death happens, I agree again. If you claim that GDP doesn&#x27;t necessarily grow exponentially, I agree again. I&#x27;d say the last one is even likely.<p>But my point was that there is no known inherent phenomena, that would force economic growth to end in the timescale of human life. End of oil could be it, or it could be offset with different energy sources, different types of consumption and more energy efficiency.
