On the basis that what is good in schools will be good for the country as a whole, and inspired slightly by Slapstick by Kurt Vonnegut, I suggest that this be rolled out throughout the country. Everyone will be allocated to a house randomly, possibly with all people with the same surname being allocated to the same house. There will be something between 6 and 20 houses, obviously they all need to have a different colour which provides an upper limit on what is sensible. Initially people will be able to change their house to someone else's e.g. partner / parent / child / whatever.
House points will be allocated on the basis of key performance targets e.g. exam grades, children being immunised against MMR, weight loss, giving up smoking. They will be deducted for speeding, driving whilst using a mobile phone in ones hand, using a TV without a licence etc.
The scores will be read out just before the national lottery draw on Saturday evenings. Indeed, I suggest that the two are coupled e.g. a band of prize (4 balls plus the bonus ball perhaps) should be given only to people with the correct numbers AND in the week's winning house.
Given the drive towards choice in education and health, someone has got to choose first, and I suggest that, on an annual basis, the first choice of school and surgeon should be given to people from the winning house.
You know it makes sense.
