You did read the post, not just stop at 'Workhouse'? From @lextalionis's post:Alcoholism and other addictions are properly classified by people with PhDs and the like as illnesses. So you want to put ill people in a workhouse?
Ignorance is a result of poor education, which society, through their elected representative, is responsible for. So you want to put people failed by the education system in a workhouse?
Perhaps you should be put in a workhouse if you become too poor to pay for private treatment if you are diagnosed with dementia. Because you will be poor, ill and ignorant.
'A workhouse should be a humane but austere and regimented institution, dedicated to breaking the wicked habits that so often lead to poverty and unemployment - alcoholism, drug use, ignorance, fecklessness, crime, immorality and dishonesty.
Work should be provided for adult members, as well as literacy and numeracy. For their offspring, if not adopted by other, better parents, they should have an education exclusively focused on literacy, numeracy and vocational skills.'
The red highlighted bit sounds like a lot of expensive rehabs which charge several grand a month to tell you to make your own bed, do the household chores and possibly general support work for the community, gardening and the like.
Aimed at breaking the habits and thought processes that may lead to addiction and certainly help keep people there.
Humane, austere and dedicated to teaching life skills, sounds a lot like the Priory and other institutes.
