Or the one that spent $24 billion dollars fighting homelessness only to have overall homelessness numbers increase? My point being California could do a lot more to fix their financial situation but cutting their expenses than trying to claw more money from people.
There's a discussion to be had about taxation in this country but I predict no matter how much revenue they make from this "one time 5% tax", they'll blow the whole thing within 3 years for no gain and then start proposing another "1 time tax" again to try and fix their coffers.
After all it doesn't matter how much money you make if you're spending more than you earn, and nothings more permanent than a temporary fix.
