The Physics departments have been made obsolete by the Engineering departments. I already noticed the trend in the 1980s.
Engineers have always made more money than the pure-science grads, and this accelerated in the 60's. Even the mathematicians jumped over, largely because if you have a talent for math, its fairly easy for you to slide into engineering, with is mostly math anyway. Just math with a real-world purpose. It's funny because, at the end of WWII, there was a big debate about where US science research funding should go. One camp wanted practical research focus with real-world goals... "Build me a generator with twice the output", etc. Lyndon Johnson famously summed up this approach with the question "What will it do for Grandma?". The other side argued for instead funding pure science research based on curiosity, and argued that practical advances would trickle down from those results. The pure science camp won for a short while, but what killed it was the Space Race. The US needed specific machines with specific capabilities on a specific deadline. "Pure Science for the principal of it" fell by the wayside to "We need that rocket to have a 60% thrust efficiency increase, next year". And it's been that way ever since. In the marketplace, and especially in the marketplace of ideas, practical engineering won. And what research we still did tended to be dominated by hyper-expensive physics projects that had practically no commercial applications at all. I think the death of the Super-Conducting Supercollider in Texas was the death knell of big pure science projects in the US. As a result, engineers are actually doing a good bit of our basic research now. It's just folded into their commercial projects.
Engineering spacecraft modules will get you a high income with steady, reliable pay. Choosing to look for particles that may never be found will not.
