Alright, but what is "middle class"? The lower 50%, as mentioned, 5.4 tons. A good part of the middle class is included in that. Mr. Merz sees himself as an income millionaire and owner of a private jet and still as part of the middle class.
By the way, this is also a huge part of the current problem. The classic enemy image of the "Green," who drives around with an electric car, lives in a KfW40 new building with a heat pump, and then flies to Bali or New Zealand for vacation because he thinks he can afford it, after all, he saves a lot of CO2 through heating and driving... And of course tells everyone about it. How can you heat with oil? That's why the polar bears are dying...
But the KfW40 new building has to amortize itself compared to the multi-family house from the 1920s first, in terms of CO2... This also applies to electric cars compared to a 25-year-old Golf IV. My ID.4 has to last 25 years first; I honestly don't believe it can...
