I agree that everyone is paying for them via the tax incentives. But I think the media portrayal is often incorrect about who benefits. The benefits of tax-exempt bonds are split between the municipality issuing them and the high-income individuals buying them. But most of the gain is captured by the municipality (because the high-income people would be getting a lot more interest in a taxable investment so the municipality would have to pay a lot more interest to raise money if they had to compete with those investments).
