San Francisco's chief economist told the court on Thursday that legalizing same-sex marriage would generate millions of dollars for the city.
Edmund Egan, who directs San Francisco's Office of Economic Analysis, said legalization of same-sex marriage would increase the intake of real estate, payroll and sales taxes and would slash the number of uninsured.
Testifying at a landmark federal trial which ultimately could seal the fate of same-sex marriage in the United States, Egan said legalizing gay marriage would also boost real estate values and increase school-district revenues.
Further, because married people amass more wealth than unmarried individuals, they are likely to spend more, spurring sectors of the economy.
Same-sex marriage supporters are seeking to overturn a California law known as Proposition 8, which limits marriage to unions between men and women. Socially-conservative opponents are fighting the lawsuit.
If gay-marriages are legalized, the city will be able to trim down the 177 million dollars it spends each year providing healthcare for the uninsured, Egan said. That's because businesses will extend health benefits to the spouses of their married gay employees, he said.
"Legalizing same-sex marriage would ultimately increase the number of people who have health insurance in San Francisco," Egan said, and that "would reduce the local burden for covering the uninsured."
Moreover, he said, citing studies demonstrating that married people are generally healthier than unmarried people, the legalization of same-sex marriage would lead to a healthier, more productive workforce.
