Where is the subject in the following dependent clause?
[...] Germany adopted a much weaker currency than would otherwise have been the case [...] (taken from BBC News)
Is "the case" the subject? I don't think so. Imagine I re-write the sentence as:
Germany adopted a much weaker currency than would otherwise have been possible
My inability to tell what is the subject in those sentences makes me feel there is something wrong?
If I try to find the subject by asking: "what would it otherwise have been the case?", I would answer the subject is "that Germany adopted a much stronger currency".
The meaning is clear but the grammar feels wrong.
Could anyone explain the grammar involved in this sentence?
This n-gram shows that "than it would otherwise have been" is never used.
Is it wrong to write the following? If so, why?
Germany adopted a much weaker currency than it would otherwise have been the case
