There is a pretty big issue here in that your statistical data is backward-looking and the choices of the high school students will matter 10-20-30 years in the future when the employment (and salary) landscape might look very different.
Maybe the Bureau of Labor Statistics's dataset includes data for past years. If Nanashi's tool allowed users to flick between the (inflation-adjusted?) data for different years, that'd illustrate vividly how salary trajectories can fluctuate over time.
Two obvious downsides: this would of course make more work for Nanashi, and past fluctuations are unlikely to be representative of future fluctuations.
Some quick background, I am putting together a non-profit whose goal is to provide objective, rational career guidance to high school/college students, with the aim to solve what I see as a pretty big problem in the American educational system: our current career guidance is more focused on how to get a job on your chosen field, rather than what field should you choose in the first place?
Mid-ranged goals involve setting up programs where students can "shadow" people who work in a field they are interested in so that they can see what those types of jobs actually entail. Short-term, the goal is to put together some informational resources that students can use to help guide their decision a little more rationally.
One of these information resources is a database that uses data pulled from the Bureau of Labor and Statistics, to tell you
