The most "productive" (i.e. productivity increase) and "booming years" (percentage wise) in American history were actually back in the later 1800s (1870 to 1900) and are associated with the Industrial Revolution. This era is known as the 'Gilded Age".
"During the 1870s and 1880s, the U.S. economy rose at the fastest rate in its history, with real wages, wealth, GDP, and capital formation all increasing rapidly.[43]"
Neither of these times are known for high taxes on top-earner incomes of individuals or business.
