It is sad to see primary education on there. I'm not sure what the situation in the UK is but in the US there are many unemployed primary school teachers and many of the employed ones make 2-3x the starting wage. worded another way, we could replace "comfortable" teachers with "vibrant" new teachers, and shrink class sizes to less than half for the same amount of money.

There are zero market forces allowed in the current system here, and this is mostly by design.

That is a really neat idea, It appears that the box is running out of gas though. It is also too bad that no fire marshal anywhere would give this thing a pass for indoor use, so it is unlikely that we will see this in the wild unless someone with a legal team builds it.
