Earlier quoted context omitted.
Absolutely not. Look at the publication record of any tenured professor at a non R1 university and you'll typically find that it's dropped to almost nil.
True, I really just meant "at R1 universities." Which isn't fair to all those other tenured professors at non-R1 universities (and I may possibly even be one, someday). Of course, I have heard of R1 tenured professors who claim to spend 50% of their effort procuring funding (though I think 10% is a much more representative estimate).
And I'm not dissing them in any way - getting a grant requires the senior/experienced guys working on it. Getting the funding is a must-have (since without it researchers and students would be dismissed and the research would not exist); but spending your own time researching is a nice-to-have thing that you can do if there's any spare time left after teaching and bureaucracy.
