Incredible, and I never heard about these enclaves.
About 5 years ago, a lot of local merchants went on a Hispanic hiring binge. If you called a store or went in, very poor English was maybe the second language.
I went on a one person protest, refusing to talk to someone on the phone or in the store unless they could speak English so I could understand them and vice-versa.
In a short time, I was getting personal phone calls from the owners, many of whom I knew.
I made my self very clear. My only language at age 70 was English. If they didn't hire English speaking people, I wouldn't come to or phone their store. Then, I would let other people know.
In many cases, I would be contacted by the owner. Non of them apologized. One even called me a racist, he closed his business in less than a year. He found out that I wasn't the only one who demanded to be spoke to in English.
My wife was embarrassed at first. After about a year, she did the same. There was a tailoring store, that did good tailoring and also made curtains and drapes. The new young owner, an American Hispanic spoke perfect English, however, his front clerks and phone people didn't. After a very bad tailoring screw up due to the language problem, my wife now uses another tailor. Her new tailor is a beautiful Latin American Hispanic Lady, who speaks perfect English. Most of her business comes from people like my wife, who tell other people to use this lady.
Harrison NJ is where the NYC MLS team has their stadium (the NY Red Bulls); they used to play in Giants Stadium in the Meadowlands, but built a smaller stadium because American soccer isn’t very popular.
In my area you can’t get jobs dealing with the public (customer service, cashiers, bank tellers, telemarketers) unless you speak Spanish or Portuguese (becuase of the de facto amnesty we’ve had here in NJ for decades); never mind 70 - most of our 20 year-olds don’t know sufficient Spanish or Portuguese to get those jobs. It is no accident that reports indicate most new jobs have gone to immigrants; they were trafficked here to replace lost generations of American children, and naturally somebody has to be able to service them as customers. Many Americans have lost their jobs to these newcomers, and nobody speaks for them.
