How about giving people an exam to test aptitude.

High IQ? You get to choose military service, Community Service or Voluntary service Overseas
Medium IQ / Conchy? Commuinty Service or VSO
Pig Shit Thick? Voluntary Service Overseas.

VSO people get sent to the shitholes overseas to try and help sort niggers problems out for them. In return for sending so much "labour" overseas, the government could justify cutting back on some of the international aid - they are sending labour after all - and what PC agency will be able to say "yeah, but they're all useless niggers"?

Added bonus? When the international aid projects start to wobble and 95% of the people there are niggers, a few more folks will get to realise just how useless they really are.

In the meantime, they cost us nothing - the host county gives them food and shelter in exchange for work. not unlike the niggers of old had when they knew their place in the fields
