The state should help people under the wheel and not those who don't need help like the fossil fuel and military industries. The state should help victims of market failure and increase revenue by closing the tax havens and corporate subsidies and corporate tax evasion. The state has a caring nature and must not become a power and security state or a punishing state or errand boy for the banks (cf. Bill Moyers). When trillions were given to Wall Street banks, that was "government interference in the free market."
Businesses should have accepted the risks and not shifted the costs of speculation and fraud to taxpayers. The corporate share in federal revenue was 40% in the 1960s and now is around 9%. John Kenneth Galbraith decried the public squalor alongside the private opulence in the sixties but we took the path of least resistance - magic thinking or wishful thinking - and pretended the market would create affordable housing.
Harvard professor Galbraith also traveled to UCLA, his alma mater, to urge voting for George McGovern and not Hubert Humphrey, the wishy-washy candidate who changed his opinion on carpet bombing Vietnam to peace and B52s.
