I suppose it depends who’s responsibility these things are, is everything the responsibility of the government and therefore their “thing” to cover the cost for, and also who you’re talking about.
Those who do genuinely need them will be unaffected, there was nothing to suggest that money is going to be taken from those who absolutely need it. But there is a movement to prevent people who actually could be working from claiming, those people will then start working and so the bill is reduced.
Provided they are also going to put support in place for helping people back into work then although short term there will be some impact, long term there won’t be. Those who genuinely can’t work will still receive their benefits, those who can work will be working. There will be an adjustment period, as with anything, because this has been allowed to spiral out of control, but the other side will come and hopefully there will be a better balance.
