Yes, as I said, I understand why you feel that couples do well. They may do, but there is more to it than that.
I feel the same about child benefit. Two working people pay two lots of commute, childcare and so on (not to mention the tax that pays for it), and a couple with one worker doesn't need a lot of that. They save on cleaners, childcare, train fares/petrol and all the costs associated with working, and pay one lot of tax. Yet people complain that there can be two people earning near the threshold who are able to claim despite the fact that they earn twice as much as the single earning couple, forgetting all the things I mentioned above. Also, there is always the option for the non-working parent to get a job, but not always an option for the dual income couple to earn more.
WRT the WFA, two people may have the heating on at the same time, but they might not. I am still up now, and my husband is in bed. Obviously the last thing we need is heating on tonight, but in December it will be different. Also, the feminist in me objects to women working all their lives and ending up subject to the whims of men, just because the men have earned more (because of historical sexism increasing their pensions). Maybe the amounts per person in a couple could be lessened? Would that make it 'fairer'?
I know all of this is just an academic argument because no govt in the foreseeable future will go near WFA with a barge pole but I do find it fascinating as to how this govt allowed itself to get into such an unfair mess. Yes I agree it’s a similar mess to what the last govt did with CB. I take all your points about two people in a house not necessarily being in the same room all the time etc and I share your views about the feminist aspects but accepting all that, a couple with a ‘joint’ income of £70 000 will almost always be better off in terms of disposable income than a single person with £35,000.01 not to mention my more extreme examples ( and I do know two couples in those situations)
Basically, the WFA system now takes a contribution based benefit (SP) paid to individuals, then at the point of £35,000 per individual turns an add on (WFA) into a means tested benefit which is paid per household . But in the rest of the benefit system, means tested benefits ( mainly UC) are based on joint household incomes( no feminist issues here) . So basically it’s just a complete mess, How could it be fairer ? Well as I said above, it won’t change now but a quick fix would be to increase the £35k level for single people or decrease it for each person in a couple. Thanks for reading as they say ( if you have thus far)
