> 99% of companies you are in a position because a company needs someone to do that thing specifically, and you might have your eye on something else internally but it's less risk for management to hire someone new into that position than it is to leave your position uncovered.

I think your 99% number is way off, I think lots of companies put internal applicants on a reasonably fair footing for lateral and upward moves. Not out of any desire to reward loyalty, but because the worker is a known quantity familiar with the internal culture, and because the fact that they are applying for such positions means it's also likely that they are considering outside positions and that if they don't get an internal job they are likely to take an external one and leave the existing position uncovered anyway.
