Not that I don't agree that Switzerland loosing its finance industry would be a big blow for the country, but let's get some perspective: Banking is less than half the size of Switzerland's manufacturing industry in terms of income - in terms of workforce it's more like a third to a quarter. In international comparison, Switzerland's service industry isn't excessively large. I'd argue the country's economy would somehow survive it.
