Yes, all of this does not just come from nowhere, there are roots that are also fertilized continuously... when you have younger generations that you get to feed (brainwash) earlier and earlier (digitally), then you'll never run out of people that think they are doing "good."
"If we understand the mechanisms and motives of the group mind, it is now possible to control and regiment the masses according to our will without their knowing it... In almost every act of our daily lives, whether in the sphere of politics or business, in our social conduct or our ethical thinking, we are dominated by the relatively small number of persons ... who understand the mental processes and social patterns of the masses. It is they who pull the wires which control the public mind."
- Edward Bernays
A new scientific [SOCIAL] truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.
