Describe Hauser's Law and what does it say about tax rates, tax laws and the raising of tax revenues in this country. Address % of GDP per year to gross revenues and why we use % of GDP when comparing across years. Additionally, address % of GDP per year that the federal government spends compared to the % GDP of revenues that it raises. You can find Hauser's law at the Hoover Institute website or google. This is merely an observational study.
