Can't comment on Paramedic level stuff, but at the EMT level, well...
At my current FD, we're only EMR level medical first response (we're trained to NREMT, but not to state certified EMT), and yet I'm doing almost exactly the same, no loss in skills than when I was an EMT-B in LA Co.
In other words, LA Co protocols leave EMTs so shackled that they're no more than EMR's in the rest of the country based on what they're actually able to do. It's not tough to imagine how similarly restrictive ALS is in LA Co to the rest of the country.
