Self ridges extravagance

London does department stores on another level!
Self ridges, Harvey nicholls, Harrods- they cater at a level that would be unsustainable in Australia. To the wealthy of Europe and Asia who seem to travel here just to shop.
These stores often have me thinking, how can there be enough people spending this much money to have these kind of stores.
Yes a stark contrast to the poverty I saw in rural areas of Rwanda.
Actually a stark contrast to what I saw in some parts of London. There must be large income gap!
