when taxes have increased dramatically since then too

No they haven't:

In 1961, families paid 33.5% of their income on taxes, but by 1969 they were paying 39% and in 1974 they paid 43.4% of their income. So, if you compare the 2009 effective family tax rate to 1961, you will find a 25% increase, but you will only report a 7% increase since 1969 and an actual decrease since 1974.

(Note this analysis is circa 2010, but things haven't changed substantially since then aside from the post COVID inflation spike that's still subsiding).
