Last time I checked, $150K was a 6-figure income. Is it not? Or has the definition of 6 figures changed due to inflation?
I don't pay any attention to salary statistics. They are completely baseless for higher-level positions. Where do the numbers come from? I would never release my salary to any statistics collection agency, or anyone else for that matter (well, the IRS, but they don't have my job description). Neither would my employer; they would be shooting themselves in the foot when it comes to salary negotiations.
The point is that physicists can make 6 figures and still do physics if they are in the right field. You don't have to be a department director for that. That doesn't mean that all physicists will do so, by no means. People just need to realize what their field is worth and decide what's important to them. Not everybody wants to make $300K/year. I don't. My current salary range is fine for me. More money would only mean more responsibility. (I hope my boss is not reading this
EDIT: by the way, many physicists take engineering positions but they still do applied physics, so that's another reason why salary statistics are completely baseless.
