A few weeks ago, I wrote a post about how we as a community can step up our tzedaka game. After following the fascinating comment thread, with highlights from Shoshana, Avigdor, David A.M. Wilensky, ML, and others, I decided to look into some of the questions about what counts for tzedaka, what doesn’t, how to calculate it, etc. This piece I wrote for Ha’aretz was the result. It focuses on the practice of ma’aser kesafim, tithing one tenth of all income to the poor. Is this a mitzvah that the progressive Jewish community could take on in serious ways?
