It isn't necessarily all that easy to change this kind of legislation.
This seems to be a real failure particularly for people at the moment who think of themselves as progressive. There is this idea that it is pretty simple and straightforward to deal with these kinds of very complicated and technical laws and acts, which have very far reaching consequences not only on society, but within the law itself.
Which is perhaps part of how we have ended up where we are, not only in the UK but across many countries. People pushing through this sort of well-intentioned, but poorly crafted, and sometimes quite radical legislative actions, that change the way so many laws will have to work, and so many systems will work - employment, education, access to health support.
Often it seems that there is very little sense of the long term, deep implications these will have, but anyone who wants to talk about them, or voices a note of caution, is accused of not supporting the vulnerable or minorities or whomever. In very much the way the GRA was treated. There is this weird naive assumption that nice legislation to help the poor people must be a good thing, and fair, and won't create any conflicts because that just wouldn't be nice.
I think that we may have entered a period where a lot of this is going to begin to unravel and in fact we are already seeing some of that in society, and it will be rather ugly.
