Many people in government are usually sheep because they do not want to change things too much because, with more risk, there is failure or the door! If one does not try something new, there is no chance of doing something better! So, they accept a few changes --at best-- that others have to implement so that THEY can be blamed if it fails.
A reform as big as a spelling reform, for instance, will be opposed by the very people who benefit from illiteracy or learning disabilities. The charitable org. want to maintain the problem. There are too many people who benefit from the status quo. It is a good gig, so let's make sure we make it last as long as possible! That is a huge problem.
