Joseph Stiglitz, writing in the New York Times, says that there is nothing inevitable about our current levels of income inequality. The whole piece is well worth the read. Here is the money graph:
The problem of inequality is not so much a matter of technical economics. It’s really a problem of practical politics. Ensuring that those at the top pay their fair share of taxes — ending the special privileges of speculators, corporations and the rich — is both pragmatic and fair. We are not embracing a politics of envy if we reverse a politics of greed. Inequality is not just about the top marginal tax rate but also about our children’s access to food and the right to justice for all. If we spent more on education, health and infrastructure, we would strengthen our economy, now and in the future. Just because you’ve heard it before doesn’t mean we shouldn’t try it again.
