> European wealth comes from exports

That's certainly a claim. The EU market is pretty big, and has multiple avenues for growth (the whole of the Balkans is either in the EU but catching up, or outside the EU begging to be let in). It's not axiomatic that the EU needs to export to the whole rest of the world. And even if it is, there are plenty of countries that have an appetite for European goods for a variety of reasons (be it luxury or just quality associations, or innate hatred of China, like in India or South Korea).

> Exactly. The European car industry only exists because China is not allowed to compete, this is my point

Alternatively, because Chinese dumping is not allowed to destroy the European car industry, if we're only talking in economic terms. But the reality is that cars aren't that simple, as a market. For many cars are a status symbol, or otherwise everyone would be driving Dacias and Skodas and nobody would be buying Porsches vs VWs.

> There is no German/French/Italian car export industry anymore. Who is buying a German or French EV when he could be buying a better car for the same price or the same quality car for a lower price.

Of course there is. Stellantis, Renault, VW Group are selling well in their local markets, across Europe and various other markets (e.g. the US for Stellantis).

> On the topic of aircraft engines. The Chinese have mastered almost every technology the west has, it is delusional to think that they will never make competitive aircraft engines

Never said never, said their own timeline is a decade, for something competitive to the previous gen, while in a decade we'll be two generations ahead. Considering Chinese aerospace engineering has been struggling with engines forever, and Russia never managed to get close, ever, I wouldn't bet on China suddenly being able to leapfrog their own timeline.

> You are correct, COMAC will take more than a decade to compete with Airbus, but with the current trajectory it is practically inevitable they will catch up.

They will catch up to ~previous generation (A320ceo), by then Airbus will already have the replacement to the current gen (A320neo, future gen not named yet). So China will still be ~2 decades behind, in a decade-ish. Yes, they will definitely catch up by some point in the ~2050s, so what? Airbus caught up to Boeing, and there is enough market to go around for both. Embraer is in the process of catching up too. There being one more new entrant on the (again, only short to medium haul) passenger jet market, in a decade, really isn't the end of the world you're making it out to be.

You are still arguing the status quo. By export I meant export to countries outside the EU, where Chinese and European EVs compete fairly.

To believe that the European car industry will survive purely on brand recognition is foolish and all current trends indicate otherwise. The Chinese are cars at the same quality for 70% if the price. That is obviously not sustainable and no amount of brand loyalty will overcome this.

None of your arguments seem convincing at all. Making worse cars at higher prices can not work. It is not a feasible long term strategy in any way.

Also, Stellantis is not selling well, they have huge problems with underutilized factories. Porsche is also currently in serious trouble.
