While I suppose it is person- and state-specific, sales tax is often a small fraction of the total state/local taxes even when the sales tax rate is high. The last time I tracked this in detail was in 2009. As a California resident, I paid ...
$13702: State Income Tax
0$3109: Property Tax (1200 sqft house)
00$997: State Disability Tax
000$41: Sales Tax (didn't purchase much)
There were other state and local taxes/fees amounting to a few hundred dollars (e.g., vehicle registration).
So the high California sales tax rate had insignificant impact compared to the high taxes in other areas. Even when I purchased a new car in 2010, the sales tax was "only" $1400 or so. Still relatively small compared to the total state/local taxes.
