Everyone wants a shot at applying for a subsidized flat that is going to be worth a million in the future. The thing is, applying for such flats, comes with it's own terms and conditions.
Start a family and the flat is yours to keep.
If you don't, or in the case of James, he can't, well, the government is always there to help.
If you can't fertilise your wife's eggs, someone else will do it for you.
