Slightly off topic, but my local council is proposing that the unemployed will have to pay 25% of their council tax bill. Now just a cursory calculation shows that an unemployed single person on £70 per week, will not be able to afford to eat. I really don't understand how this works, are we really trying to starve people to death in this country? (bear in mind that unemployment benefit is not based on what you have contributed) so you could have been made redundant, divorced, any number of calamities, and now your faced with a death sentence. I am all in favour for people working, but this country seems to have gone back about 150 years recently.
The mistake you make is to look at only 1 beneifit and go "How can they afford this".
When in fact they will receive a number of benefits, including a benefit set up specifically to pay peoples council tax.
