Translation:
Socialist eduction for everyone because of our great Capitalist system.
Our system is rotten at the roots. It's unsurprising that things are going the way they are.
My, you're optimistic. The education system mentioned in the film pre-existed the days when all teachers had been force-fed Marxism. Many of my teachers were devout Christians and patriots who served our country in WWII or Korea. We still had the pledge of allegiance, real American history and Bible readings in school up until the 60s.
Our system depends, as de Toqueville observed in the 1840s, on a virtuous population. When we still had a Christian middle class before the Democrat Socialists' concerted effort to change that through overwhelming all systems with unbridled immigration and relentless elevation of deviance (the Cloward-Piven strategy), our schools were much more locally controlled and were populated by families who expected one another to stay married and care for their own children and elders according to Western moral traditions.
In the 50 years since this cartoon was made, having recognized the strength of our traditional morality, the communist-inspired ACLU and its international socialist puppetmasters made a strategic plan and a concerted effort to dismantle all the key institutions in our society. And they have nearly succeeded because not enough patriots could or would imagine the depths of depravity to which the left would stoop -- no shame on them for that. The awakening that is happening now may be too late.
But it may be soon enough. I prefer to encourage the push-back, not condemn and surrender as you have done.
