I have a question which relates to the discussion of this post:
What is the timeline from graduating with a BSc to becoming a full professor? How long does the PhD take? Postdoc? Assistant Professorship? etc...
You ask tough questions. There is a wide range of individual variation, depending on the subject, research area, available funding, positions open, institutional policies, publication rate, and sometimes simply how well you get along with the department chair (I've seen more institutions implementing more formal guidelines to offer some protection for the faculty in that last case, but it's still a factor in a lot of places).
Time to obtain a Ph.D. is anywhere from 4 to 10 years (most schools I've been at have 10 years at the cut off that if you haven't completed it by then, they throw you out). Five to six years is most common, with a few struggling along a 7th year if something in their original project plan went so kablooey they practically needed to start over.
Post-docs usually last until a faculty job can be found...it's a stepping stone. Some only do them for a year or two, others end up in a long progression of post-docs lasting 6 or more years (this is rare, but if one graduates at a time the field is saturated and refuses to change paths, they can get caught in that holding pattern for a while).
At the assistant professor level, usually there's a time clock for getting tenure...move up or out when the timer goes off. In most places, that's 5 years, but often with one chance to appeal/reapply if you miss the target the first time, which can buy another year or two. So, no more than 7 years (if someone is absolutely outstandingly productive with bringing in multiple grants and publishing copiously, they might be able to come up for tenure early, but it's really rare).
The remaining two levels of associate professor and full professor are not defined. Some people will never get past associate professor for the duration of their career (I see this mostly with people content to just teach and not too worried about maintaining active research so that they never reach the next publication level and international recognition requirements for promotion to the next level). Others will do it in another 5 years. Think of it like any other career...if you're motivated by promotion, you'll work your butt off to achieve it. If you reach a level in an organization and salary that you're comfortable with, and decide you would rather be passed over for promotion in favor of having some free time to live your life, you're not going to work as hard to get that promotion. At that point, promotion doesn't make a lot of difference anyway. It does in terms of salary, but you're certainly not hurting for money as an associate professor. Your job is already as secure as it ever will be, and it makes no difference in anything else you can do as faculty (actually, as soon as you're hired on as assistant professor, salary and tenure is the only difference between you and a full professor in terms of what you can and can't do within the university...you can still serve on all the same committees, vote on policy changes, teach the same classes, bring in graduate students or post-docs to work with you, etc.; which is why I don't at all understand the comment earlier that it's a caste system, and can only think it's from someone who is not employed in academics.)
