You’re comparing pop-culture with religion.
While I agree that modern advertising (which has spread in politics) creates new religions, you’re mixing inner value with commercial value. These are commercial religions.
The Harvard study on happiness, which has been ongoing since the ’30s, shows that human relationships make people happy. Not amusement, productivity, art, knowledge or even wisdom. And pop-culture, trendiness and in general, commercial religion, is focusing on gimmicks. Gimmicks don’t tend to last long.
Regarding the last paragraph, I’m quite speechless.
