I identified precisely the largest component. The component that is and has been lacking.
Growth is slow as a result. Obviously that's where the problem lies. The other components have grown over the same period and have not stimulated growth.
First you say consumption is the largest component, and then say it has been lacking. What makes you so sure of that? Oh of course, we should believe you the great liberal economist central planner, who is so amazing at economics that he could not run a lemonade stand!
Damn.. the regressive arrogance.
Secondly, the other components ARE growth by definition, so your claim that they haven't simulated growth is completely nonsensical. Clearly you have absolutely no clue.
I agree though, let's reduce government spending so C and I can rise, that actually leads to greater growth over the long term. Can't disagree with that! Perhaps there could be sanity to your plan after all.
