So I figured I'd check what the other largest European companies are. In order: LVMH, Novo Nordisk, L'Oréal, ASML.
#4, ASML, is of course the pride of the Dutch tech industry. That's a company that's innovative on tech and making its profits entirely by making the best chip manufacturing machines.
#3 L'Oréal is primarily known for shampoo and cosmetics and that sort of stuff.
#2 I hadn't heard of. Apparently they mostly provide diabetes care. That's awfully specific for such a big company. No idea if they're big because they're incredibly innovative in that field, or that they're monopolising healthcare.
LVMH's name suggests it's not a company that grew this big naturally, but it rather the result of several mergers. An artificially inflated moloch.
I think most people here would be happier with ASML in the top spot.
