They're not true monopolies but it's close enough in many respects
BMW, Daimler, VW all stuffed into one $4.3t economy. It'd be like if GM and Ford were ten times larger than they are in relation to the size of the US economy.
Scaled up to the US economy in size, those three would be up around $3 trillion in sales (five to six times the size of Walmart).
So they're co-monopolies, towering over the German economy, sharing it all with one or two other giant German companies. I suppose that's nice of them, sharing is caring.
well kinda. bmw basically is owned to 46% by two people and they control it. vw the same, most voting stock is in the hands Porsche Automobil Holding SE, basically owned by wolfang porsche, his ancestor was ferdinand porsche.
yeah on paper they are traded. but not controlled. (mercedes is different here) but a lot corporations in germany are at least still controlled by descendants
