That graph still isn't big enough to show our GDP growth and it needs to be adjusted on a logarithmic graph to better show the trend (to get rid of the exponential component):
As you can see, any dip that you are showing is nearly irrelevant to the steady state economic growth path. Perturbations can be as large as 15 years.
Notice in your graph the blue line is converging back with the red line off the chart.
This is wrong for several reasons. Above all else, your last argument is saying that the success of stimulative policies should be used as an argument against stimulus. haha.
All that aside, my graph wasn't intended to show trends, lol. It was intended to show that Bush was deficit spending at a time when real GDP growth closely matched potential GDP. ie: it was wasteful. Obama was/is deficit spending at a time when real GDP was substantially below potential GDP. People were attempting to argue that the two were equivalent, which they obviously are not.
Given what we know about fiscal multipliers, it should be obvious why the first is bad and the second is good.
Second, your chart not only doesn't support your argument but it's misleading as well.
1. Your chart ends right at the beginning of 2010, meaning it only includes one year out of six years of depressed GDP growth. If you're going to try to analyze trends you can't possibly show up in the graph you provided, as it only includes about 15% of the trend you're trying to analyze. That's a big no-no.
2. We're talking about a several percent change in overall GDP. That's very meaningful in real terms but you're trying to get people to eyeball a change like that out of a 120 years of economic data by using such a large graph. That's extremely misleading.
I could go on, but considering that this wasn't even about analyzing trends that seems pointless, no?
