They're protecting property owners at every step. Why haven't they condemned large/tall buildings with inadaquate stairwells for fire evacuation (in fact, given the timeline of the fire, Grenfell's single staircase would have been amply adaquate to evacuate the building before people started dying)? Because that would totally hose the people who own such buildings. And why aren't they requiring large buildings to have adaquate staircases? Because that would eat into profitable floorspace. The UK prioritizes property owner profit.
