Tribe 12, a Jewish group that claims prominent business and public leaders like trade publisher Irvin Borowsky and Montgomery County commissioner Josh Shapiro among its backers, says it's planning to open Tribe Commons, a "co-working" tech development center "rooted in Jewish community and values."
"Our mission is to create a Jewish network based on both a common need and desire to succeed as independent professionals and entrepreneurs, and to be part of a Jewish community of like minded individuals," founder Ross Berkowitz says on the group's home page.
Is this progress? For a long time Jews were among the groups made unwelcome in Philadelphia's leading banks, law firms and country clubs; like others, they built their own. By the 1970s those barriers were coming down; by now ethnic firms and even the clubs have merged and faded.
Tech, in particular, has been a sort of American meritocracy where immigrants - many of them South Asian Hindus and Muslims, East Asian Buddhists and secularists - combine and compete with Americans of all backgrounds. Why divide?
