William Petty,
A Treatise of Taxes and Contributions…
“ Wherefore wholly rejecting the said complicated way of Tax, I shall speak of Poll-money more distinctly, and first of the simple Poll-money upon every head of all mankinde alike; the Parish paying for those that receive alms. Parents for their Children under age, and Masters for their Apprentices, and others who receive no wages. 5. The evil of this way is, that it is very unequal; men of unequal abilities, all paying alike, and those who have greatest charges of Children paying most; that is, that by how much the poorer they are, by so much the harder are they taxed. ”
