I'm not saying that it was a good thing but there used to be an idea that claiming benefits was a bit shameful. Which was a terrible attitude.
And benefits were for the most in need.
But the pendulum swang too far in the opposite direction and became all about what people are 'entitled to' and not what they need.
So you have people saying they won't work because they'd only be a few quid better off a month than claiming UC.
A poster on MN a few months ago was taking in £3700 a month in benefits because of a child on DLA meaning no benefit cap and full housing benefit etc as her rent was almost £2000 a month.
PIP was designed primarily for the physically disabled who had extra costs caused by their disability. But is now overwhelmingly claimed for mental health and ND conditions. Some of whom are in work and some who aren't, many of whom are using it as additional income and putting it into savings as it's non-means tested so you can be a millionaire and claim it.
My Grandmother bless her has recently gone into a care home and hasn't worked since the 1960s but with her widows pension, state pension and PIP has managed to accumulate 100k in savings because her outgoings were minimal in comparison to her benefits.
