Two adults living together should get a tax break because their expenses are less? How about people who live in shared accommodation, or hotels, or prisoners?
I think prisoners get £20,000 of expenses free! There's no council tax or utility/tv bills in hotels, & isn't it the Coalition forcing single men into shared accommodation? The issue with that anyway is it's transient, isn't it.
What have you done with Dandelion!!!!
Have you been Clegged.
From a quality of life point of view, fewer, better houses are more preferable to the endless urban sprawl, mainly derived from single person dwellings. Just look at how many former school playing fields, brownfield & urban green areas have been built upon.
From an economic point of view, it's a complete waste of money building new houses, aside from building to replace, or for a definite rise in the populace.
Fiat Capitalism depends on people buying things they don't need, that they can't afford, with money they don't have, & I've long harboured the suspicion that a lot of social engineering tries to fracture relationships in order to duplicate the number of products/assets bought.
Furthermore, in the UK, it can cost the state a minimum of £10-15,000/annum in extra benefits paid out when couples split up.
So, relationship break ups, & more dwellings, cost more, makes the place we live look less desirable, it's inefficient, & is environmentally poor (& you must know how ungreen I am:smile

.
Therefore, especially in these dodgy economic waters, it makes sense to keep people - & families - together under one roof. Money problems are the number one reason for break ups - & lead to non economic concommitant socia, emotionall & personal costs that then affect wider society; so have a heart Dandelion -it's in all of our interests:smile:
Most prisoners are forced to work at wages far below taxable level as part of their 'rehab'. They are even used as telemarketers nowadays.
In the UK they can't really work - the unions put an end to that in the 60s.
