I agree it's a huge concern and I also absolutely don't trust the CDU, and especially Merz, as far as I can throw them. However I'm just saying that the situation is not identical to the USA, there are some points of difference.
The mid-right said they wouldn’t work with them, but as we have seen that means absolutely nothing. I wouldn’t be surprised if the SDP CDU broke that and started working with AfD.
I'm also very worried about that, but it's another point of difference - there were historically enormous protests (tens to hundreds of thousands per city, well over a million total, more than a percent of Germany's total population) several times recently because CDU looked like it was slightly cooperating with them with an informal and unbinding agreement about immigration. These protests had the support of the churches, the sports leagues. Various senior government figures support outright banning the AfD. It would not be as easy for them as in the USA, where everyone immediately capitulates.
But yeah I agree it's a political difference and not just about "education", you're totally right about that.
Let's be clear here, the right extremist party got over 20% which is really bad for sure, but the mid-right party rules out working with them in a coalition no matter what. That's rather different from where the rest of the republicans and many democrats fall over themselves to do whatever the lunatic fringe says. Further, the American billionaires are strong influencers of these trends in other countries. The core of the disease is the USA even when there are symptoms everywhere.
That money only really makes wealthy Americans better off in living standards though, someone making 35k in France or 40k in Germany has a vastly better life than someone making 80k in a mid-high cost of living area in the USA.
