There is no money in tools because employers (and to some extent employees) don't value them. Also, folks who make tools maybe value them too much? And maybe tools are too easy to copy?
I remember decades ago when purify came out. I tried the demo at work on a project I was working on. Within a few hours, I found an enormous number memory errors. It was enormously helpful. Purify had a high per-seat license cost, and work wouldn't buy it.
Many current employers are a little smarter about things, but I mainly see things like code coverage tools and version control systems, but no real spending on more personal/fashionable tools, even if employees are more efficient.
I think tools that might work better would be those employees bought them themselves - think jetbrains - and priced accordingly. The analogy might be auto mechanics building up their collection from snap-on.
also, warts and all, linux is a nice environment because you can get to the bottom of most things and tools might be less industrial quality, but there are plenty of them.
