Questions on postdoc

[Comp]

How tough is competition to become a perma faculty member at a third tier uni or better? Are there tons of brilliant postdocs to compete with? How many, 2, 5, 10, 50? How brilliant, just good or very good?

Also, how much time in % do you estimate is spent on doing non-research as a postdoc? Such as lecturing, teaching grad studs, administration, grant writing? I imagine you get like 80% of the time to research, the rest goes to other stuff? Is math particularly different in this regard compared to other fields such as CS, theoretical physics, etc?

Furthermore, it the academic landscape likely to change for the drastically worse in 5-10 years time? You know, increased competition from China and India, national budget deficits, faculty retiring...

Reason for asking is I'm considering going into research.

You probably won't find any phd's here. Dan, the owner of the site, is still a master's student. We've mostly got undergrads & high school students.
