Even if the jobs available are manifestly unsuited to the claimant's abilities or needs?
If graduates or people with years of managerial experience are on the dole and told they must take up shelf stacking jobs or go and work in Amazon's warehouse (where the conditions are appalling, incidentally)....what do the people who would normally take those jobs - those without much experience or formal education do? Wait for the more skilled people to leave when the economy picks up?
When I was on JSA I would have taken a very dim view of anyone telling me "take this job (which suits you in no way and which you are never going to stay in) or we will stop your £70 a week", especially given the NI contributions I'd already put into to the system precisely to protect me (and others) in the event of finding myself without work.
Demonising the unemployed is a disgraceful state of affairs, one this government are happy to encourage. The same as they have encouraged many people to enter very low paid employment so that despite there being record numbers of people in work, income tax receipts are still miles under forecast as millions of people earn next to nothing.
