No, you're saying that other people are wasting your time by not learning effective ways to communicate. They shouldn't expect you to do anything you've expressed no interest in doing.
> Expecting things to stay the way they are isn't compatible with economic growth
Your points are incoherent and make no sense. Economic growth was huge in the years after WWII, and remained stable for a long time without massive changes. And then you segue into cultural change from economic growth? Give me a break.
If you are an immigrant, you're making a change in your environment because you didn't like the way things were in the place you were moving from. Not learning the language or the customs in the place you're moving to is expecting things to stay the way they are far more than people who stay put in one place.
Basically, if you move, you probably have a good reason for moving. Don't try to transplant the way things were in the place you were to the place you're moving to.
