I have a question about the use of the subjunctive in this sentence: If all the schools were to implement this program, which now exists only in the lower grades, then five years from now we will not have parents complaining that their teen-aged children still can't read.
There are a lot of internet examples that follow this pattern. Example: If that were to happen, then we will take appropriate action.
Would it be better to substitute "would" for "will" in both examples, or "should" for "were to"?
