Lucy Hood misses a major point. The tech industry has grown in Los Angeles on its own.
She wants tax breaks and investment incentives "to make Los Angeles the global technology center that it could become." She describes the growth that has occurred without subsidies. She wants the mayor to appoint a chief technology officer who would raise venture capital money (there is no dearth of private companies that do this) and bring together leaders in academia and industry (as if mutually beneficial relationships are hard to set up).
I'd take every penny Hood wants the city to spend on subsidies and bureaucrats and, instead, use it to lower business tax rates and maintain the city's roads and infrastructure.
