"My point is this: the reallocation of capital is possible. The evidence is that tax has a massive influence on how people save. And right now the vast majority of the benefit of the tax subsidy that savings get goes to the wealthy, the financial services industry and those who speculate in land and buildings. This is not socially useful activity and it is a dire waste of tax subsidy. So we need to reallocate that tax subsidy to align tax policy with what has to now be the biggest priority of society - which is saving the planet. That is all I am suggesting: that we shift the subsidies that we offer from banks and financial services companies and speculators to the creation of real work for people who need it creating the sustainable future that we must have. And I suggest that we can fund a Green New Deal as a result."
