Tax day realities

From Practical Economics

A look at historical trends offers some answers to the question of how much taxation is
sufficient for government to accomplish its necessary functions efficiently. Research has shown
that for America’s first 130 years, federal spending as a percentage of GDP averaged around 2.5%.
Since 1915, or for the next 75 years, spending consistently rose as a percentage of GDP and
averaged around 16.6%. Current spending is approximately 19% of GDP. The historical shift
above traditional norms in government spending and the associated increase in involvement in the
economy came during the Depression under Franklin D. Roosevelt’s administration prior to the
outbreak of WWII. This time frame forever changed the political landscape and philosophical basis
for expanding government’s involvement in the economy that continues to this day.
