I was once driven north along Central Park, all the way from Chinatown. We hailed the cab in front of a building where Orthodox Jews still lived, so they shut down an elevator on Saturdays. In the taxi, I was with my mother. We were visiting her aunt, my great aunt, who was 93. She had no memory of the old country, Lithuania, but she'd been born there. Her parents escaped the pogroms so she could survived a century here. Her American prosperity was half a century of subsistence wages and thirty years of Medicare in an elevator building. The old country for the cab driver was Bangladesh, and he was a talker. He'd just graduated from college, and his prospects were good. He'd majored in a practical field, network engineering or something like that. Young and optimistic, he spoke fluent English. His big idea was to keep his countrymen out of the United States. America was great, but if he got overrun with foreigners, his kind in particular, it would be ruined. "Bangladesh is hot and crowded. Why would want to make America like that." He said this in all sincerity.
