If you are asking this question, you don't understand some critical things.

That might very well be true. I have invested a bit more thought into the Spiral Dynamics model of developmental psychology and extrpolate on that basis with the information that Wikipedia provides about Kegan's model.

But when it comes to polticians Wikipedia lists "Culture of mutuality. Mutually reciprocal one-to-one relationships." for stage 3 and "Culture of identity or self-authorship (in love or work). Typically: group involvement in career, admission to public arena." for stage 4. Being driven by wanting to increase the wellness of people in general seems to fall more into stage 4 than in stage 3.
