Under Henry VII, John Morton was made archbishop of Canterbury in 1486 and Lord Chancellor in 1487. He raised taxation funds for his king by holding that someone living modestly must be saving money and, therefore, could afford taxes, whereas someone living extravagantly obviously was rich and, therefore, could afford taxes as well. Morton's Fork may have been invented by another of Henry's supporters, Richard Foxe.
