Gross is silly you need to talk net. Living wage in California is like 37k before taxes 43k if you include taxes on that and assuming a tax rate of around 25% of the rest that means you have excess take home of $22,500 a year.
$2,000 a year would be around 10% extra income not related to staying alive.
I wouldn't call 10% a minor deal.
Also your point about 1-2% cost shows why this is a good bill. Cover the things you need to, pay a few points of payroll and get a significant benefit for your employees.
