- Let banks operate and merge across borders, especially neobanks/fintechs. European banks are easily 10+ yrs ahead of the US in terms of tech and customer service but they lack scale and capital, especially in the credit side of things.
- Credit, again: we need the equivalent of D&B/Fico for Europe: a single credit bureau that can judge creditworthiness of people and organizations. Even the US has solved this through private companies, why can't Europe? Fellow Euros are shocked when I tell them that a 0-day LLC in the US can get $20k in credit card limits almost immediately.
The rest are easy, especially for web/internet companies. But if we have to raise credit/money based on the rules of the biggest (and slowest!) economies, then the EU is fucked.
