The problem that needs solving is what is the right action to take for SEN /disability that over the long term reduces the cost of supporting them for the state.
Ultimately there simply isn't enough money /not enough people currently are contributors to the state, so a way has to be found to support these groups to be able to work/contribute more than they are doing now, even if it's not at the same level as the rest of society.
The idea is supposed to be that increased funding during the educational years would result in some of these individuals then becoming more able to take on paid employment, or able to live in a more independent way that costs the state less in support.
But it's not working. Despite spending loads more money, fewer and fewer of these individuals with SEN or disabilities are coming out of the education system able to take a paid employment, and costs to the state for people's living /care arrangements (eg via PIP) are only increasing.
So then you necessarily have to question if it's the right use for all that money to spend it on SEN support etc in schools if it is not improving outcomes?
Could it be better spent on money in the healthcare system perhaps, for treatments, therapies etc?
That's the problem governments trying to solve, how best to spend what money is available to deliver the best outcome
