Sergey Brin's invention saved my vision, analyst says as Sanders targets $82M tax push

Google co-founder Sergey Brin is spending $82 million to defeat California's Proposition 40, a one-time 5% wealth tax on billionaires. Senator Bernie Sanders slammed the move as a "moral obscenity," saying Brin would rather see low-income Americans suffer. But policy analyst Patrick Hedger defended him, crediting Brin's search engine with helping find a doctor who saved his vision after four others failed.
