Mother Goddess vs Patriarchies, revisited

Just on that theme of Mother Goddess vs Patriarchies, it's usual in mythologies to absorb the past, to build upon previous beliefs. We are mostly talking about spoken-word stories of course. For a very long time mankind could only pass along such information by camp-fire story-telling, and even when we invented writing only the elite really had that knowledge. In some places it remains so. Thus persuasive story-telling was it.

So why the change? Why move from balanced beliefs where 'good and evil' could equally be male or female, to a patriarchical system where male gods did the good stuff and the female ones were either watered down or made to do evil?

Was it a conspiracy of priests? Of Kings? Was it related to the general shift from an agrarian existence to a wealthier, more specialised type of city-state existence, where fighting wars across vast distances became the norm? And so we needed to persuade many men that it was right and noble to march in armies across the known world, for king and country?

There was another shift here, too. Mother-Goddess religion was about 'do this and this at the right time and the evil (e.g. a famine) will go away, allowing the good (i.e. rain, good crops) to naturally reappear'; whereas the patriarchies were (and are) about 'doing stuff that we ask of you because we ask for it, and in return we strong male gods will protect you from evil'. A less-than-subtle subtle shift from expecting good to flow from the earth to a sort of protection racket. This one change distanced man from nature and allowed us - to this day - to rationalise just about any abuse of the environment or ourselves.
