DITW I think you are fighting a losing battle. In principle I agree with the changes but unfortunately people will get caught out unfairly but you can't bring in sweeping changes without some casualties, nothing is ever fare for 100% of the people. There are safety nets, charities, government bodies etc to help people in need and I expect this policy will end up getting tweaked along the line.
As the majority of the population is in work I think that the government (rightly or wrongly) will have the support they need to carry on. There is no opposition in this country Labour have nothing to offer, no alternatives just hot air.
You can't keep knocking the wealthy and blaming them for everything, wealthy people create jobs there is no shame in being rich, if you keep 30 or 3000 people in work why should you be persecuted because you have wealth. If labeling everyone on benefits as scroungers is wrong so is labeling everyone who is rich and successful as the devils spawn.
