I'm from New Zealand. What's our major companies? None of them employ more than 20,000 employees globally. Sure that's a lot of people to lose a job, but the big companies are building, groceries, airlines, and telecommunications. If the companies go under, the demand for the products doesn't disappear.

As for unemployment rate, 3.9%. Pretty close to the UK, USA, China.

As for tax, on $100K USD, you'd be taxed 28.3% on your income, and 15% on your consumption via GST.
