Oh dear - political dogma introduced to the thread ! Wonga is a limited company not a PLC and all the shares are owned by the founders or private equity companies. The Tory government has a lot to answer for but left wing lies don't help the situation at all.
Hardly the same though is it ? I assume you've brought your home outright with cash ? You of course wouldn't dream of renting as all that does is put money in the pocket of the corrupt capitalist profit making pig landlord !
Rather than banning them advertising the government should put a cap on interest that can be charged for credit. Obviously it would kill most of the payday loan industry overnight though.
