It is a massive problem and all under the guise of ‘our culture’. I get it somewhat but equality won’t happen if you keep it this non equal on the basic level. I get that you learn a language when you move (I did a bunch of times), but it will never get better than my english or of course dutch (my native tongue, although I am starting to forget words after having been abroad over 20 years); all my colleagues do speak english but refuse because of culture they say. I feel this is a pretty basic issue and a massive problem.
