What I'm interested in - the statement you described as obviously false is not obvious to me - is whether or not tax rates were always much lower than what they are now.
The only info I could find quickly isn't much, but makes my point: http://www.whitehouse.gov/omb/budget/Historicals/ Table 1.1.
Sampling (in millions of dollars):
Year range_________________________ Total federal revenue per year (ave for range prior to 1940)
1789–1849 (61 years) ____________________________ 19
1850–1900 (51 years) ___________________________ 284
1901-1915 (15 years) ___________________________ 630
1916-1940 (25 years) __________________________ 4,015
1950________________________________________39,443
1960________________________________________92,492
1970_______________________________________192,807
1980_______________________________________517,112
1990_____________________________________1,031,972
2000_____________________________________2,025,198
These numbers are not adjusted for inflation, but since inflation was only a big factor after we went off the gold standard, and clearly cannot account but for a fraction of the growth seen above, these numbers are still a good indication of the stark difference between the early history of the U.S. and the last century.
And you're right, import tariffs were the bulk of revenue for those early years, and as you can imagine, they didn't add up to much, since it applied only to imports. But like I said, nothing even remotely comparable to government as we know it today existed in the U.S. at that time.
Edit: I know this isn't exactly what you were asking, but I don't know of any reasonable way to directly compare the "rate" of taxation, since GDP data and the percentage of income spent on imports subject to tariffs are not readily available for those early years. But since the difference in total government revenues is so stark, it's reasonable to deduct that the difference in total effective tax rate is comparable. And we know that only a tiny fraction of the current budget is more than sufficient to do everything that government did back then.
