Islam came to liberate humanity from all kinds of slavery -- and vices. And it did so quite successfully.
Among the top modes of slavery Islam set humanity free from were Hereditary Kingship and Traditional Priesthood.
In fact, Allah had kept Pre-Islam Makkah more or less free from these two most terrible vices, even though the rest of the world wallowed in them.
But Muslims, being Muslims, went right back to the drawing board and changed the basic message of Islam to fit their dominant value structure of the day: modern-day slavery to kings and priests with all kinds of fancy names.
Today, Muslims are about the only people in the world who have real, live, fully functional and absolute monarchs and kings, who completely own them and their lands and their resources, and who are the most unquestioned and absolute rulers of the lands they occupy.
Muslims also have a rich mix of priests even though they call them by all kinds of fancy names. These new-age Muslim priests with fancy new titles exercise extraordinary influence on the lives and destinies of Muslims most of whom are naive, ignorant and ill-informed about Islam and the world.
Thus, having totally changed the basic teachings of Islam, in two of the most fundamental areas of life, Muslims then run around asking everyone why they are in the terrible mess they are in.
