What you're describing is "idealism" - the idea that people's ideas are not conditioned by the material conditions of their lives. That doesn't seem to be true. Instead, "The ideas of the ruling class are, in any age, the ruling ideas". Most people believe the things that are necessary in order for the conditions they live under to perpetuate themselves. People's ideas change mostly as a result of change in their material conditions.
After the Great Depresson and the second world war, most capitalist countries put brakes on those feedback loops in order to keep the whole system functional, especially in view of the apparent success of a socialist alternative. But those brakes have been in the process of being gradually stripped away since the 1970s, and even faster since the failure of the Soviet Union.
