Diversity in the Valley

I've often commented on the interesting diversity of our area citizens. Last weekend, at the Mountain View Art and Wine Festival, I passed groups and individuals from many countries who make this a more interesting place to live. All along Castro Street, there were Asian, Indian, Italian and Spanish restaurants and shops of all kinds, but the signs were either in English or bilingual.
Recently, an area of Santa Clara attempted to change its name to "Koreatown." Many of the signs along El Camino Real in that section are in Korean only, and complaints are that this encourages not diversity, but exclusion. In Santa Clara County, 51% of the residents speak English only, as opposed to 81% in the U.S. as a whole.
While I understand that it is more expensive to have signs made in more than one language, even a small, less expensive sign in the window of a shop would make people of other backgrounds feel welcome...and isn't that the whole idea behind owning a business?
When my family came to this country from Europe, the first thing they did after finding jobs and a place to live was to enroll in school to learn English. While I can relate to the need to keep the customs of a family's homeland, I agree with Sam Kumar, a restaurateur in Santa Clara, who said, "What connects us all is English."
