I take your point about the government loan accruing interest, the interest
then being paid by the government, to be absurd, given that one cancels the
other.
However, I would argue whether there should be any
interest being charged at all. Historically it wasn't and if I were able to
find a job, I'd have no problem paying the interest and would in all
probability seek a remortgage to pay off the statutory charge in full.
As I receive help paying interest on my mortgage which secures my
home whilst not working, I do not see why the interest on another charge
over my home would not also be considered.
The government is
very familiar with giving with one hand and taking with another in any
event
