Why don't construction prices go down?

Then you just take money out of Switzerland instead of bringing it in :) Top!

Yes. Because Switzerland follows the same model as Germany: predominantly selling high-quality products abroad, which in turn takes on the role of the debtor in the national economic accounts. The foreign countries slow down -> capacity utilization declines -> the economy weakens. What else?

Here we are again, back in dreamland...

Which high-quality products do we still sell in significant quantities abroad? Foreign countries are mainly slowing down with us because they can now produce the high-quality... or at least sufficient products for their own population themselves and no longer need the "high-quality" stuff from Germany...

And if we delve even deeper into the matter... and leave the level of the local politician with an economics degree... The "high-quality" products from Germany are now produced about 90% outside Germany. According to German plans, but the "others" have those as well...

German "high quality" largely consists only of a highly paid, semi-skilled worker assembling components produced in China or East Asia under the guidance and supervision of automation and tightening 5-10 screws per station... they don’t trust him with more screwed connections, then it becomes too complex for the 4,500 EUR gross earned at the assembly line...

After all, there are still about 1,300 (potential) world market leaders in various fields, mostly located in medium-sized businesses and to a large extent also producing here. Even in my small town on the Lower Rhine with a little over 20,000 inhabitants there is one - and of course also producing in Germany.

What other high-quality products do we still sell abroad in significant amounts?

At least those of the hidden champions. Just take note of the figures: The trade balance surplus really exists. It wouldn’t exist if we didn’t export a lot and especially more than we import.

Abroad is mainly easing off on us,

Yes. That’s what I’m saying: The German business model is like a junkie hooked on foreign demand. But foreign countries are slowly replacing it with their own domestic demand – you’ve explained that yourself.
As a high-wage country, you cannot create this foreign demand (which we call competitiveness) by adjusting labor costs. It simply doesn’t work. Innovation or nothing. And companies don’t innovate when labor becomes cheaper.
Germany’s enormous surplus has been a thorn in the side of the rest of the world, as one can read internationally for two decades(!). Because there must be corresponding deficits somewhere. The USA have primarily provided them through national debt. Or what do you think the purchasing power comes from that buys German products?

Germany certainly lives on debt – just not its own. And others are slowly getting fed up with it, see Trump.

Because there must be corresponding deficits somewhere as a mirror image. The USA has mainly provided those, with national debt.

The discussion is almost six decades old. Back then, the question was whether the world could tolerate a second version of an export world champion alongside Germany with Japan.

I know. The international discussion among experts is also completely different from that among the German provincial economists. However, what the German provincial economy has caused in people's minds through decades of constant bombardment is shown here by some comments. Less money in the citizens' pockets (wage restraint, cutting citizen’s money, etc.) means even less domestic demand and even more dependence on foreign demand – although this dependence is exactly the problem. But if you simply call this dependence by another name, namely competitiveness, suddenly it sounds so sexy that everyone wants to participate. The world has been pointing out exactly this problem to Germany since who knows when, and in Germany there is a discussion completely detached from this. It's crazy.
