I guess that something had to be done as the costs are unsustainable - and rising..
It is devastating for those genuinely in need, no doubt about that, but there are many gaming the system. PIPs are a case in point. They have been too easy to get and are there for life when many should only be temporary until the 'emergency' is over. That has only been partially addressed in that they will now be harder to get yet some could be made temporary, as was once the case. Reorganising the agencies involved is also a decent move as there was so much duplication.
The problem for the government, all governments, is that once something is given it is hard if not impossible to roll back or remove them. They become an expectation rather than a genuine need, but to try to change things makes them "heartless" and "immoral" according to those against such moves.
I don't have many problems with what is being attempted so long as those who really need help are protected and do not inadvertently fall through the net. That will be a big test under the new system.
