The financial sector must be put in it’s place now
The financial sector has imposed huge externalities on the rest of society. America’s financial industry polluted the world with toxic mortgages, and, in line with the well established “polluter pays” principle, taxes should be imposed on it. Besides, well-designed taxes on the financial sector might help alleviate problems caused by excessive leverage and banks that are too big to fail. Taxes on speculative activity might encourage banks to focus greater attention on performing their key societal role of providing credit.
Over the longer term, most economists agree that governments, especially in advanced industrial countries with aging populations, should be concerned about the sustainability of their policies. But we must be wary of deficit fetishism. Deficits to finance wars or giveaways to the financial sector (as happened on a massive scale in the U.S.) lead to liabilities without corresponding assets, imposing a burden on future generations. But high-return public investments that more than pay for themselves can actually improve the well-being of future generations, and it would be doubly foolish to burden them with debts from unproductive spending and then cut back on productive investments.
