The Grenfell fire was caused by petty corruption. Someone involved in its construction used a cheaper flammable cladding material instead of the (slightly!!) more expensive fire resistant version.

It’s very on-brand for places like Russia and China but clearly western countries are not immune to this kind of thing either.

After the fire there were investigations into towers constructed here in Australia. Many used the cheaper flammable cladding material also. Just like with Grenfell, nothing much was done and nobody went to prison.

What does that have to do with the actual idea that being in a tall building could make it difficult to escape. It doesn't matter if the cause of the disaster is cheap building materials or an external force acting on a properly built building.
