Theory Z can be rather related to the growth stage developement process, wherein on atainment of a particular age, one does not wish to take risk in life, looks for long term peace and enjoys lighter side of the event rather than involving in depth and consuming problems. A higher side inclination to Theory X and intrinsic value formation attachment to Th.Y to some extent. But the energetic involvement during the initial ages into explorative mood could be attributed to intrinsic motivation tending to Th.Y pattern and on the other hand at higher age level, leaving aside tougher things and enjoying lighter things can be an inclination to Th.X. So this Z Theory, is nothing but an integrated approach to Th X and Y if we account based on aging fator. This supports my research on 4359 persons of varying ages in Indian conditions.
