2. Goody One Origin

“Good Two-Shoes” is a neologism developed in 1765, and describes an excessive do-gooder. However, the original children’s tale from which it comes, Goody-Two Shoes by John Newbery, is at heart a Cinderella story, which tells of Margery Meanwell, who humbly makes her way through life with only one shoe. A rich man rewards her with another pair, instilling the earning of wealth as a sign of virtue.

Based on a comparison study of tax records conducted by two Italian economists, the richest families of Florence in 1427 were still the richest families of Florence in 2011.
