With policies like this, why would anyone in their right mind (I say this as a staunch progressive) start a business in SF or even consider traveling to the Bay Area for the benefits of huge equity packages? Even if you choose to willingly ignore that CA state taxes are also increasing substantially.
I hate to say it, but when you do things like this to Big Business TM it DOES have trickle down effects that negatively affect small business owners and business services alike.
