Interestingly, what you see as completely normal (other taxes) was once as disturbing as capital tax seems to be:
> Window tax was a property tax based on the number of windows in a house.
> At that time, many people in Britain opposed income tax, on principle, because the disclosure of personal income represented an unacceptable governmental intrusion into private matters, and a potential threat to personal liberty. In fact the first permanent British income tax was not introduced until 1842 [note by me: not until 1914 in France!], and the issue remained intensely controversial well into the 20th century.
