The pappies are myopic and have a single-track mind.
They think that by playing the Population Ponzi game, economic growth can be achieved indefinitely and all social costs can be swept aside (a karaoke session organized by the grassroots Integration Council will surely endear the new citizens to the born and bred Sinkies).
The root cause is greed and paranoia, caused by a lack of wisdom, which made them treat citizens as economic digits, rather than human beings.
If you're still not
angry by now, check if you still have a pulse.
