From what I have encountered, it seems to me that the meaning of "concern" and the passive voice of it "to be concern" is very often the same.
1. The problem concerns us.
2. The problem is concerned with us.
Does it seem rigth to me?
And can I say:
"This TV programme is concerned with economic crisis."
Regarding the sentence above, is the sentence:
"This Tv programmme concerns the economic crisis."
If yes, does it mean the same as given in previous post?
