Austerity is violence
It's not for the proletariat to clean up the mess of the ruling classes.
A little camping trip in Hackney might raise £500k. If we cut tax evasion in the UK by 1/3rd for just one year, you could buy every single homeless kid a house. And of course that would do little to resolve the underlying problem. Many kids are broken by abuse and trauma, and will require state support their whole lives one way or another (eg: ending up in prison).
The ruling classes are selling weapons, promoting wars, and laundering the proceeds though property and tax havens. They are fucking laughing at us. In the face of such malevolence, there is nothing you can do to alleviate the environmental stresses that cause mental illness in children. Not this, not anything.
