Very small countries are an anomaly, specially in Europe. They are usually tax havens, trying to attract commerce and business from the neighbours. Andorra, Monaco, Liechtenstein, Gibraltar...

You could see them as parasitic economies, sucking money through their borders. They can be that way because they are not big, so the drain in the resources of the neighboring countries is acceptable, while they give some specialized services mostly to the higher classes: hush-hush banking, casinos, cheap electronics, luxury vacations.

Luxembourg is bigger and has more of a real economy than say Monaco, but still it has these kinds of tendencies.

Do you believe that privacy for banking should not be allowed? Because your post reads as such? Switzerland is an excellent example of a country which is highly stable (past 500 years) near zero interest rates. Highly trained and armed populace (14 soldiers per square km versus the USA <1) They maintained neutrality during ww1 and ww2 and have continued.

Banking privacy is very important, why should anyone know how much money I have after I declare my income for a given year and pay taxes?

and there's the rub. The main reason people love bank secrecy is it allows them to hide income.

Why not?
