Deciding to live in a country and not even bothering to learn the native language of that adopted country is extremely selfish and disrespectful to that country and its people. People who refuse to learn our language have no business emigrating here. Proficiency in English should be a requirement for U.S. citizenship. End of story.
Some side-notes as I had some experience with Kodak in their glory days...they were once considered to be in the very top tier of American companies and had the same dominant position in film/cameras that Apple has today in the mobile device field. Kodak was sitting on thousands of patents and their future was extremely bright. To work for them was considered to be set for life. But they made some extremely poor decisions. For example, it was Kodak that invented the digital camera! However, they decided to put it on the shelf and not bring it to market out of fear it would cannibalize their dominant high-margin film business. We know the rest of the story. Digital cameras eventually exploded in the marketplace and in a very short time, the film business was all but completely wiped out. Then Apple put a decent digital camera on their iPhone and went on to wipe out most of the digital camera industry. Very disruptive changes in the industry and Kodak did not react in time - even though they had the original technology!
A note on Apple, a few years back, my son, while pursuing a computer engineering degree, applied to work at the Apple Store, thinking that would get his foot in the door to work for Apple itself. No go. He was told that Apple Store was operated separately from Apple corporation and that there were no career paths from one to the other. I found that hard to believe but apparently it is true, if you wanted to work at Apple corporate, you had to apply from the outside and your job at Apple Store did not give you any kind of inside track. So essentially working at Apple Store is a dead end for those wanting to work at Apple corporate. I think that is rather short-sighted as many Apple Store employees are very bright and passionate about Apple products. They should have a path to work at Apple corporate.
Here’s a good way to never advance in your career in America: never learn English.
I grew up with a housekeeper who even cleaned my room. Sweet lady, from El Salvador, didn’t speak a word of a English, just a few broken phrases. I left home, went to college, went to France for a year, traveled the world. Married a chef, moved to Europe. Came back.
I now spoke two new languages fluently and a third heavy dialect very well, enough to be thought a native sometimes.
AND THIS WOMAN WAS STILL UNABLE TO SPEAK ENGLISH AT ALL after all these years. Picture a steaming face emoji here.
