Not always great at linking sources, I do admit. It's usually because I read a report, the figure sticks in my head, then weeks later come across a thread. I do TRY to go back and find the links when I have time, but I sometimes forget if the thread drops off my active convos! 
How can it be unrealistic to expect that the cuts will be thought through fully, and the impact on the people affected fully discussed, and NOT leaving anyone in poverty? I truly believe that in 5 years time, we will have some parts of the UK that have Victorian levels of poverty in some families. That is just plain WRONG in a developed country in the 21st Century. Especially when some people earn millions / practice tax avoidance / own more homes than they NEED, while others in the country will not have even their BASIC NEEDS met.
IMO, it is just GREED on the part of the people at the 'top' of the pile that leaves others in poverty. While we may not YET have widespread levels of poverty like there was in the Victorian era, I'll bet that's changed in 5 years time. And that's OK? With ANYONE? There WILL be people who lose their homes and are unable to get another. There WILL be people unable to EAT if they want to keep a roof over their heads. There WILL be greater strain placed on the NHS by people suffering from diseases of malnutrition. There are already people that have had to rely on food banks to survive due to cuts in disability benefits - and have killed themselves due to the grinding, abject poverty they found themselves in. Is that REALLY what people think is OK? When we are wasting millions on the Olympics, and HS2, and the probable new London airport? It's NOT that there isn't enough money there - it's that it is being spent on the WRONG things. Things that only benefit the people at the TOP of the pile, NOT the people down the bottom.
OK, I am no economist, and I have never said that I am - but I just believe that if everybody had enough to survive, and anything that was earnt above that was taxed to provide for that, then no-one would go hungry, no-one would need to be homeless, and anyone that went out to work and earnt money would be better off than those that didn't, albeit not by as much as some are! And there wouldn't be the massive disparity between the CEO of a company's wages and the wages of his office cleaner. It works in Japan.
