This will be a good opportunity for their codes and enforcement to be brought up to North American standards.  But I agree that it won't provide justice for the victims.  Justice should, and undoubtedly will, be obtained through the courts.  

But to turn this into a rant against income inequality is just crass opportunism, turning it into a class action grievance by those other than the residents who suffered loss.   A fancy hotel in the Gulf region using the same materials goes up in flames, and there's not one word about income inequality.  Instead, the focus is on codes, materials, greed of developers, lack of enforcement, etc., and justice is resolved through the courts.  How is that any different than with Grenfell, other than the socio-economic status of the victims (and their neighbours)?
