Well, they HAVE money, they do not need to earn it ;).
The Malfoys have been sort of wizard gentry for supposedly centuries, time 
enough to gather magical objects, buildings, knowledge and connections that 
bring money into their vaults without actually "working". Malfoy is great in 
networking, we can see this many times in canon, and one can be sure that 
the Galleons the Malfoys spend on welfare will repay.

Apart from this, JKR didn't plan or describe the economical system of the 
Potterverse. She invented a currency (the currency system being a parody on 
the old UK Pound system), she made some families rich and others poor, but 
the rest is imagination for us readers. I wouldn't recommend diligent 
research on how the Potterverse economics could work - JKR's not only bad at 
math ;).
