There are many things that effect economic growth but they are all weighted differently. The most important are Taxes & Credit quality/access. If you have a 100% tax there will be zero economic activity.
100% wrong. All taxes get spent and therefore contribute to the same economy.
You clearly have a 2 dimensional grasp of a 12 dimensional economy.
The Laffer curve has very little to do with the growth of the economy btw. It merely measures tax revenues generated under different tax rates.
What you speak of is another animal entirely: a optimum tax rate curve that co-relates to maximum personal income or gdp.
But again taxes are only one driver of GDP, income or tax revenues.
The Federal Reserve is the federal agency tasked with the specific job of regulating GDP growth and they seldom even bother to consider taxation. Because they consider taxation a miniscule driver of Gdp.
they consider interest rates to be the primary driver of GDP growth/contraction. And lending and money supply, money supply velocity etc.
You have an extremely remedial grasp of economics.
just saying, not trying to bust your chops.
