How bold you are. That does not mean you are correct, though. Archie Bunker called them like he saw them, so what?
As it so happens, I have a Slavic sister-in-law who came over here on a green card and eventually married my brother. When I first met her, her English was pretty sketchy.
In the twenty plus years she has been here, she managed to obtain a masters degree for which she had to write a theses. She now teaches her specialty at a small state college.
She also is fluent in five languages. What is more amazing to me is that 95% of the time, you would never be able to tell she wasn’t born here. Not only does she have practically no accent, she has all of the idioms down.
Could she have accomplished all of that without good English skills? Perhaps people who marry billionaires are more insulated from the effects of less than perfect English skills.
But for most of the rest of us, they are crucial. Anyone who says that heavily accented, and ungrammatical English is not a severe disadvantage in the job market, probably is only used to hiring janitorial staff.
I am also a volunteer literacy tutor who works with ESL students. I know of what I speak.
And this will be my last comment on this thread.
