I can remember when New Zealand and Australia would NOT let anyone into the country unless they could add to the overall improvement of economy, business, professional such as medical .... and so on ...!
You could not have an entrance unless you had an exit, without a resident sponsor.
What is this .... is it just time for the bad guys to make their move and negate all that was good and safe ....
When did the people , of these countries, lay down their arms and good sense and say .."here it is .. come and take it .. all you want for free ...?
That seems to be the world protocol ... except for the people ...
