Tories discuss stripping benefits claimants who refuse treatment for depression

From today´s Sunday Telegraph:

http://www.telegraph.co.uk/news/politics/conservative/10964125/Tories-discuss-stripping-benefits-claimants-who-refuse-treatment-for-depression.html

According to the government, 46 per cent of benefit claimants receiving Employment and Support Allowance, the main benefit for ill and disabled people, have mental health problems.
...
Estimates based on government figures suggest the state spends up to £1.4 billion a year – more than £3.5 million per day - on ESA for these claimants with mental health issues.

That's 260,000 claimants.
So if you can cure 50% of them of depression at a cost of £2700 per person, the cost will be £700m and the benefit will be £700m.

For £2700 per person, I will happily volunteer to be the therapist.  And I only need to get a 50% cure rate.

Tory MPs allege that claimants are just unwilling to avail themselves of the services available.  Obviously they don't know that the waiting list for CBT is several months in many areas, and the alleged benefit of CBT doesn't kick in for 6 months anyway.
