I live and work in London since I moved here 20 years ago. You would be surprised how many people are well paid in City of London to be able to afford properties. I dont doubt for a second that many had help from families and many properties in London are owned by old money but for what i know, 90% of the colleagues have more than one property in London and mostly through their own salary/saving. The average salary before bonus in City of London is now 70K meaning a couple should be able to buy a 500K flat after a few years saving. And this is not high flying industries like bankers or lawyers who could buy faster.
