> For example, a lifetime IC job may be ultimately worth less than a management job that gets you to VP level in a decade

How are you positive that you can get to VP level in a decade as a manager? That doesn't sound easy. Just by looking at the number of managers and number of VP in my company it would seemed that around ~2% would eventually become VP if the ratio hold, that's an incredible standard for "reasonably good". Doubly so if you are not even starting from the same track.
