Some clarifications:
1. Presumably you don't have to satisfy everything in each level to be considered satisfying that level; otherwise if your entire family dies in a plane crash, you can never achieve MH3 again, and if you never got MH5 before that, you're permanently fucked.
2. If you get to MH4, but then your town gets hit by a neutron bomb, killing your wife, family, and friends, you get your MH3 knocked out, but your MH1, MH2, and MH4 are all still intact (MH4 because you telecommute most of the time, so your career is intact). Are you immediately eligible for MH5, or do you have to regenerate your MH3 first?
3. Interesting corner case: Say you get to MH3 by virtue of being raised in a rich American family. At age 18, you fly somewhere to visit a college by yourself, and your entire city gets blown away by a neutron bomb. You now have no friends or family, but life insurance on your family pays off handsomely, so you are at MH2. You decide to become a soulless driven businessman, and you do fine; you get promoted, everybody respects your competence, you respect other people's competence, etc, but you have no friends and no companionship. It would appear that you have reached MH4, but you never got there while you had MH3; does this count as MH4? Or do you deny the possibility of this scenario? (I made it up, so that's perfectly valid.)
(These are not leading questions; I'm curious as to how the Maslow viewpoint deals with corner cases.)
