Let's compare the workforce of countries with an ageing population and rapidly dropping net population with countries like Australia that are absorbing 250k immigrants per year into "self employed" (read: rich third worlder's buying a house and a passport) of course you're going come up with a figure like that.
Throw in some countries with massive populations who have also got an ageing population but have 20x the population of Portugal to make them look bad on absolute numbers and you have a winner. Of course a tiny change in employment is going to look amazeballs or on the other hand terrible.
The difference is..being in one of those countries right now but from the greedy nation of Australia is that sustainability is practised. It's not all about greed here. You don't need to destroy the planet to have a family here so seriously a big middle finger to anyone who thinks that Europe not growing is a "problem".
