I think the problems with Fry's and Radio Shack and every other electronics supply store here in the US is that nobody is interested in tinkering with electronics anymore. Only a few of us old guys, and much fewer young guys. Now people want dancing robots and AI and smartphone apps where you click a button and it does your laundry while you sit on your butt.
The closest most tech people get to real electronics nowadays is watching a 5 minute video on how to connect a Raspberry PI so you can have a $50 computer. We're getting further and further away from the hardcore tech stuff and all we can do is be expert button pressers.
As usual, no, it's not about bad management at any of these large corporations. It's about customers no longer being interested. And they'd much rather pay a fraction of the price and have it delivered from China rather than keep US businesses afloat.
It's our fault, nobody else's.
By the way, have you noticed that the vast majority of "tech" video channels have ultimately changed over to being more entertainment-based? That's what people are interested in. Entertainment, not tech. They want "Oooo, shiny !!" new hardware (preferably with flashing lights), and stories about how their house got damaged in the cold wave, and rants about NVIDIA.
