Why did the Squid Games movie become so popular? Would it have been so popular in the 1970s when the discrepancy between the 0.1% and the median were at the lows of the cycle? What is its memetic value and how something becomes viral? 

Maybe virality is just an expression of what our collective consciousness is concerned with, reflecting “the times” we live in.

The popularity of the Squid Game movie can be attributed to its reflection of societal issues such as income inequality and the struggle of the common people. Memetic value and virality often stem from resonating with the current collective consciousness. It's a cultural phenomenon that captures the essence of our times.
