I think that the economy grew in the 1950s notwithstanding the top tier marginal tax rates because the rest of the world was still recovering from WWII; we had the majority of the world's manufacturing capacity, logistical capacity, etc., and half the world's population was effectively taken out of the picture by the Iron Curtain, Communist China, Indian post-colonial isolationism (and flirtations with socialism), and so on.
Maybe, but then there are the 1960s. And the test cases for low top-tier marginal tax rates would seem to be the late 1920s, the late 1980s/early 1990s, and the mid-2000s to the present day -- and with friends like those....
Like I wrote, GDP growth fluctuates for lots of reasons. But the clear-cut "taxing the rich kills growth" claim just doesn't jump out of the aggregate numbers, over time, at all.
