in case you didn't know.. Muslims paid that tax too.. it was just called another name(zakat) it was obligatory for Muslims, too.. And it was of the same amount the non muslims paid.. 2.5% of income.. so Muslims paid zakat 2.5% of income.. and non-Muslims paid jezyah.. 2.5% of income...
I know we paid up to 35% of income for taxes in the U.S!
