Sure, as an overall amount of stolen money... errr, taxes, Taxifornia gets obscene amounts of money from we the people.  You're right about the population being a key factor, but it's not just the population, it's also the tax rates.  We pay the highest marginal tax rate of any state, resulting in one of the states with a top tax burden, and we have the largest population of any state.  So, combined, those make a pretty devastating combination, tax-wise.
Of course anyone reading this may have noticed I said tax rates, as in plural.  I wasn't just talking about our outrageous tax brackets, because out here if it moves or stands still, Dims tax it. If it's yours and the money that bought it was already taxed, and you sell it, Dims tax it again.  If it doesn't even actually exist, Dims try to tax it (referring to unrealized income)
If you're really wealthy, say over a million per year income, the nominal income tax rate can be as high as 14%.  I'd like to be able to personally complain about that one, but I don't earn enough.  Still, they rob me blind, too.
Then throw on an additional 9+ percent sales tax in many counties (certainly here in the bay area) and a plethora of other taxes, fees, surcharges, parcel taxes, a motor tax, of course excise taxes like our insane gas tax, etc.  Not coincidentally, we have the highest gas prices in the country to go along with the 62.5 cents per gallon gas tax, and along with county and local gas taxes.  Add it all up and we pay almost $1 per gallon in gas tax.  91 grade premium is still over $5/gallon where I live (Santa Clara county).
My favorite is the "use tax", which means, I guess, that they're taxing you for using something.  For example a car.  You buy the car, drive it for however long, then sell it.  The money you get from the sale has already been taxed before you bought the car, but the Dims tax it again at 7.25% - 10.25% and call it a use tax.
And of course, being kind to our oldsters, Taxifornia taxes retirement income at the same rate as non-retirees' income.
And if you only earn $10 K per year, Taxifornia wants $100 from you.  So much for caring about the low income folks.
All anyone needs to do to figure out what the federal govt will try to tax next is to look at Taxifornia.  Because those taxes will be coming to a govt near you soon.
