There goes civilisation...

You can't blame somebody for buying something if they have the money to do it! What about all the people who own the equivalent of 5 bikes in parts? Or all the girls who love shoes and handbags? Are we going to blame them for pushing up prices?

the availability of easy credit is fundamentally the doing of those that lend, there is a certain proportion of so called 'liar loans' but often these are pushed by the brokers or at least the ability to pay not researched properly.

i haven't seen the 10%+ year on year price increases on bikes (dunno about handbags) whereas the 6x income mortgages as opposed to the historical norm of 3x and unsustainable rises in property prices are only possible if the banks allow it.
it's their fault. the banks created this mess and most likely the taxpayer will be financially ass raped.
