I agree that it seems ridiculous that the sons and daughters of the well-healed can claim benefits but I think the fact that unemployed post- uni ex students can claim benefits is as a result of them being counted just the same as any other independent adult who is expected to work for their living and pay their way in rent and bills.There really isn't a way of the government distinguishing between those with generous families and those without.
Many ex-students are lucky that their families are willing to take them back into the family home without even charging them rent but many many others don't have families that will do this (or can afford to). Some ex students living back home are expected to pay for their own food, rent etc despite having mummy or daddy's mansion roof over their heads. It amazes me how many threads I've seen on MN with parents being advised not to support young adult dcs after uni, or to charge them the equivalent rent they'd pay for a flat plus bills if they ask to come home because they're adult and they should be taught to stand on their own feet etc, plus lots of comments about apron strings and cocklodgers when it's a ds rather than a dd coming back.
The same issues of unfairness crop up with some wealthy families topping up their child's student loan and others refusing to do so. I guess it's almost impossible for the government to measure how much support a young adult gets from their family.
Bigbluebus I'd be tempted to collect your ds by car. As Xenia says, the rules now say we are allowed to move house and personally I'd count a 4 month move home as long enough to be a house move rather than visiting family. Plus, car travel is safer for everyone than taking public transport so your ds coming home by train seems the worst option.
Student end of tenancy dates are rapidly approaching so most students wont have the choice that your ds has of staying put. There has to be some common sense on this one!
