According to a December paper from University of Michigan economist Adam Stevenson, gay marriage would bring in $20 million in Michigan. So if every state made that much it would be $100 million. But keep in mind New York made $158 million in ONE year. And if California legalized it it would be an estimated $123 million in three years. While if Maine, Maryland, and Washington would bring an estimated $166 million in three years. So $100 million + $158 million + $40.6 million + $54.8 million = 353.4 million, that is in one year.
