>"These internal barriers mean Europe has many smaller firms operating at national, not continental, scale. Each country tends to have its own banks, utilities, airlines and supermarkets. (Europe has over 100 mobile operators, compared with a handful in America or China.) These lack the economies of scale and opportunities to grow quickly enjoyed by firms plying the American or Chinese markets."
Europe has no homogeneous consumer market for tech giants like the US or China which can propel tech firms to gigantic size. And honestly I consider this a feature instead of a bug. It seems like profits aside the major other thing they seem to promote is damaging competition, democracy and pushing surveillance. If it was up to me Europe should use the decline of business giants to double down on the idea of the 'Europe of regions'. Small, diverse and robust business that does well on international markets, pays attention to its stakeholders rather than just shareholders, and does not just pursue growth blindly.
