This. ^ It's a myth that benefits are large and generous, and as you say, 100s of 1000s of people who had to apply and live on them for 6 months (or more) had a massive shock.
As did those who had their own business/were self employed and had cooked the books for a number of years (and got £70K a year but only declared £24K a year to the taxman - as the rest was cash in hand/hidden.) They were knocked sideways when they 'only' got 80% of the £2K a month they declared to the government!
Yeah, being on low pay/benefits is a wake up call for those who have been raking in £80K to £95K a year or more net pay. These are the type who cry into their pillow because their DH's job changes and his salary drops from £90K to £65K and they have to give up the cleaner, or cancel the installation of the orangery.
Utterly UTTERLY clueless some people. I remember a woman I met once whose DH was on £135K, and he bought her a Mercedes Benz for her 40th birthday, saying she wouldn't be able to cope if he had bought her a 10 year old Astra like we had, and would be embarrassed to be seen in it. And was knocked sideways when someone else we were talking to said her DH brings home £1200 a month. How do you SURVIVE she said. My DH brings twice that much home a week. 
Farcical.
