I must confess that when I saw a citation to the Heritage Foundation, I felt obliged to verify this through other sources; it seems about right. Also, it's an interesting exercise to view https://en.wikipedia.org/wiki/List_of_countries_by_tax_reven... which has a table is sortable by rate. You can see, for example, which states get revenue from oil, and have very low taxes but perhaps little incentive to diversify, and other interesting stuff. Looking at the extremes really makes me wonder how some societies operate.
