> This kind of flexibility in the labour market is clearly an advantage because the US and CH have some of the highest salaries and lowest unemployment in the world.
It really is quite a big stretch to assume that this is a causal mechanism. You only need to look to Scandinavia to find a counter-example.
I think it is more reasonable to argue that high salaries in US are fuelled by borderline slave wages for menial labour. And Switzerland's wealth comes in a historical context that is completely different from the US - it's almost impossible to blanket compare them side-by-side. The difference in population size is another huge issue with such a comparison.
