The Tories have
never
tried to verify whether punishing unemployed people for every
failure to carry out the job search dance really led to more of them
in employment.
I'm not surprised that the Tories have not tried to measure the
"effectiveness" of these punishments in achieving their supposed
goals, because the goals don't make sense anyway, and I don't think
the Tories were honest about their goals.
I think the Tories' real motive for these punishments is to demonize
the unemployed and the disabled (often labeled as capable of working,
through a carefully arranged system of excuses to disregard their
medical evaluations) and to
make
it seem they don't deserve any help, which in the long term serves
as an
excuse
for ceasing to help them. That will "save" money, making it
possible to further cut taxes or increase welfare payments for the
rich.
As for the non-rich unemployed and disabled, with no state help they
won't live many more years, and the Tories will say, "Mission
accomplished."
