(Part of it is I think we should make it easier and more incentivized to learn the language early so not just people in english-dominated tech jobs can have a positive experience. Cold start problem. It shouldn't be too hard for the gov to commission a RosettaStone like german learning app ((suboptimal, i know)) that works somewhat well and give it out for free, right?)
But a struggling economy, questionable planning for many years now, the "educated middle class" he mentioned in the post shrinking don't bode well for it. It's a prime breeding ground for scapegoat politics. It's probably one of the cognitive "exploits" in the human mind, that finding a scapegoat (the foreigners) to blame for everything being such an effective tool to rally people with grievances behind yourself and slowly turning them into hateful monsters.
