Generally, I think philosophy is like mathematics in that while its purest application is very obscure and very hard to understand without a whole lot of effort, that pure application results in practical breaththroughs on almost every level of "practical" research. I wish that pure philosophy was taught to more people, just as I wish that we taught kids more than the boring "practical" math that convinces them math sucks and patterns are boring. It's a pursuit that benefits nearly everybody who learns from it: reshapes our mind, teaches us new ways to observe the world. And if we had scientists, psychologists, programmers, and politicians learning philosophy, then there'd be less pressure on the actual philosophers to start studying something practical.
For me that's the change that should be made: not more practical philosophy, but more philosophical practice.
