Currently it is too easy to pin GDP to the top of the chart, and there is to little benefit from it. I have had GDP pinned for years now, despite the global GDP rising and falling, yet I still have unemployment about 40% of the way up the chart, and revenues are rather lack luster despite significant tax rates.
In general, it should be more difficult to raise GDP, and there should be more benefit for successfully doing so. I won’t spam 40 detail suggestions, but please look over it.
