Grenfield tower is yet another example of the great divide between rich and poor, and the power and arrogance of global companies. 
This cladding was known to be unsafe, yet some company has marketed it and sold it to dozens, perhaps hundreds, of hotels, developers and councils around Britain for use in multistory buildings for which it was demonstrably unsafe. 
Over a hundred years ago two of my forebears were caught in the Stanley pit disaster of 1909 where 168 men lost their lives. It was caused by a large Davey lamp that was approx 2ft wide. Lamps over 1ft wide were known to be unsafe yet the company continued to use them until the explosion occurred. My g-g uncle and his son aged 14 were both killed in the Tilley seam and another g-uncle lost his leg in the rescue attempt. Two weeks later my g-gmother was evicted from her house with the rest of the children because she no longer had a husband working in the mine. 
Things haven't changed.
