I propose that any such question should be rephrased as follows:
Where can one find salary data for job type X / country Y / field Z?
If the question is just "What is the salary range?", then what would an answer look like? If it just gives specific figures, then it can't be expected to be valid into the future. If it comes from someone's personal experience or guess, then it's purely anecdotal. What you really want are statistics based on large-scale data from a reliable source. So if such a source exists, then why not simply link to it? That way, people will be able to find well-referenced data into the future (assuming the source continues to update their data, which many do).
Also, if the source turns out to give a broader range of data (covering multiple job types / fields / countries) then the question can be broadened retroactively, so that people searching for any relevant combination can find their source in this question, and not have to ask separately.
This way, instead of giving people fish, we're teaching them to fish, or at least telling them how to get to the river.
