I don't know why anyone would pay more tax than they have to. If there's a loophole, they will use it.If they paid a fair rate of tax (ie not practically nothing) in my State/Country they’d have more funds for social housing too.
Paying tax should not be voluntary, Apple! As individuals we can’t get away with it. Why should you?
Do you ask your accountant how you can pay more in taxes? I certainly don't. If there's a way I can reduce my taxable income, I reduce it.
Actually, a more relevant question is whether you trust the people who spend your tax money.
California has had liberal tax and spend policies for decades.
Are you happy with how the money is being spent?
