Ditto what BG said about public and private employment and the opportunity to move up or increase your compensation.
More anecdotal stuff, but when I worked in the private sector, I quickly advanced from an entry level position to management, and was able to multiply my compensation many times over within a few years. That’s VERY difficult to do in the public sector.
If they are going to compare things like “job security,” then they need to include the opportunity for advancement (and the opportunity to earn bonuses!), too.
