Despite its flaws Squid Game was fucking awesome. And yes, I know all the source material that came before it, but SG is a fusion of primarily Japanese sensibilities with Western and Korean. This is what allowed it to break out, because as in nature, hybrids, when not retarded, are more vigorous.
As to why the elites are pushing it? Korea is at the jewed staged that America was at circa 1970-1980. So what they need the Koreans to do now is turn their back on the economic prosperity that they had achieved. This will split the society and create turmoil through which jewish agents will be able to seize economic control and bleed the South Korean cash cow dry.
On the world scale, you see the same themes pushed as always. You can't trust your best friends. North Korea and China are evil. Rich people are evil. There's also the demoralization message that everyone chose this fate themselves...no one is innocent.
And oh yeah, Christians are all portrayed as useless and complete whackos. That alone would get a series pushed to the Netflix top rec list.
