Do you have an example where you think that the masses have organically fallen into sin, rather than it having been induced by the authorities? It doesn't seem to happen that way much if at all.
COVID delusion and negative environment - imposed top down by media and government
Social degeneracy, sexualisation - imposed top down by the red media
Proliferation of masturbation - laws changed by government to permit it
Secularism, atheism - enabled and promoted by government
Mass immigration - enabled and promoted by government and the media
Rootlessness - enabled and promoted by the government and the media
Stealing from the future (unsustainable welfare state) - imposed by the government
Abortion - ditto
We used to have more moral authorities that held these things at bay via moral leadership. It does appear to be the case that without moral leadership, the masses will decay of their own accord. But we have not simply had moral leadership removed, but replaced with immoral leadership.
You can see the masses will be melded into whatever environment the authorities create, e.g. Nazi Germany, Christian Europe, Islamic Spain. And that environment very quickly changes if a new authority establishes itself.
If a country suffers as a result of rampant abortion and immigration, those are two things that were enabled and promoted by elites, and they were able to do so as they had already reduced morality previously. We are in a procession of elites removing morality and replacing it with morality.
You could say that the declining behaviour of children and children gaining some power over their parents is an example of bottom-up power. But it is merely a case of authority shifting from parents to the red media and schools. In our re-worked system, programmed children have more authority than their parents, who are at least a generation behind the decline.
The only example I can think of where I think the masses have considerable weigh is in their demands for a welfare state and to be taken care of. This appears, to me, to be all the authorities need to provide to keep the system in place. People will take vast degradation, so long as they are materially comfortable. But that itself appears to be a manifestation of the current environment, which was created by authorities.
@Samseau quoted The Bible some time ago; a passage in which most of the people were described as sheep, and the fruits of the sheep depend on their shepherd. Bad shepherd - bad fruit; good shepherd - good fruit. It seems to me that the sheep have next to no agency and the agency they have is within the confines of whichever pastures they have been led to.
