A major theme of the underlying political debate in the United States is the role of the state and the need for collective action. The private sector, while central in a modern economy, cannot ensure its success alone. For example, the financial crisis that began in 2008 demonstrated the need for adequate regulation.
Moreover, beyond effective regulation (including ensuring a level playing field for competition), modern economies are founded on technological innovation, which in turn presupposes basic research funded by government. This is an example of a public good – things from which we all benefit, but that would be undersupplied (or not supplied at all) were we to rely on the private sector.
Conservative politicians in the US underestimate the importance of publicly provided education, technology, and infrastructure. Economies in which government provides these public goods perform far better than those in which it does not.
But public goods must be paid for, and it is imperative that everyone pays their fair share. While there may be disagreement about what that entails, those at the top of the income distribution who pay 15% of their reported income (money accruing in tax shelters in the Cayman Islands and other tax havens may not be reported to US authorities) clearly are not paying their fair share. ...
I have to disagree with the second sentence of this next paragraph. And I think Stiglitz knows better, if he stops to think about it:
Democracies rely on a spirit of trust and cooperation in paying taxes. If every individual devoted as much energy and resources as the rich do to avoiding their fair share of taxes, the tax system either would collapse, or would have to be replaced by a far more intrusive and coercive scheme. Both alternatives are unacceptable.
The billionaire investor Warren Buffett argues that he should pay only the taxes that he must, but that there is something fundamentally wrong with a system that taxes his income at a lower rate than his secretary is required to pay. He is right. Romney might be forgiven were he to take a similar position. Indeed, it might be a Nixon-in-China moment: a wealthy politician at the pinnacle of power advocating higher taxes for the rich could change the course of history.
But Romney has not chosen to do so. He evidently does not recognize that a system that taxes speculation at a lower rate than hard work distorts the economy. Indeed, much of the money that accrues to those at the top is what economists call rents, which arise not from increasing the size of the economic pie, but from grabbing a larger slice of the existing pie.
Those at the top include a disproportionate number of monopolists who increase their income by restricting production and engaging in anti-competitive practices; CEOs who exploit deficiencies in corporate-governance laws to grab a larger share of corporate revenues for themselves (leaving less for workers); and bankers who have engaged in predatory lending and abusive credit-card practices (often targeting poor and middle-class households). It is perhaps no accident that rent-seeking and inequality have increased as top tax rates have fallen, regulations have been eviscerated, and enforcement of existing rules has been weakened: the opportunity and returns from rent-seeking have increased.
Today, a deficiency of aggregate demand afflicts almost all advanced countries, leading to high unemployment, lower wages, greater inequality, and – coming full, vicious circle – constrained consumption. There is now a growing recognition of the link between inequality and economic instability and weakness.
There is another vicious circle: Economic inequality translates into political inequality, which in turn reinforces the former, including through a tax system that allows people like Romney – who insists that he has been subject to an income-tax rate of “at least 13%” for the last ten years – not to pay their fair share. The resulting economic inequality – a result of politics as much as market forces – contributes to today’s overall economic weakness.
