Social Psych Q: Does leadership style influence the growth and progress of its constituents, global scale?

[Generalist]

This question is deeply felt and well considered.
There are so many facets that it is difficult to pick from the storm of considerations.
Islam did better than Europe at the time when Europe was a set of warring absolute monarchies and became frozen in time under the Ottoman Empire. The Renaissance distributed individuality concepts and blew the lid off the world.
Philosophies that foster contributing to others, rather than controlling them, produce far greater results in almost all environments. That is true for the individual as well as groups up the scale of size.
Fear and intimidation engender frozen learning. Contributing to people's development produces superior results.
