>invest more relative to their passenger load.

For Switzerland does this account for the almost double salaries or only absolute spending?

If you spend 1€ in Switzerland I imagine you get much less work output than for 1€ in Germany.

Raw investment numbers don't necessarily matter, but the productivity of said number. Even if things are more expensive in Switzerland, if they make efficient use of said investment, then it can work out ok (or even better).

I have no idea if this is actually the case, but you have to take that into account or Switzerland would not be as successful as it is. Higher incomes have historically been a symptom of productivity (and while median incomes and productivity have decoupled, especially in the angosphere, it is still usually correlated).

		>Higher incomes have historically been a symptom of productivity If I go to Zürich I get a burger for 30Fr that I can get in Southern Germany for 15€ and in Berlin for 8€. That is with roughly the same quality. I'd say past productivity leads to network effects and investments in one area that boost local salaries and decouples them quite strongly from current productivity. My previous company had a per-dollar extremely unproductive location in silicon valley. The people there weren't at fault. You don't magically become more productive because you live next to SF.
