> One big problem is that over the decades the economy has shifted more to services and less to sales of physical goods, so sales tax revenue has declined disproportionately.

This is also the reason why the rich won't leave places with unusually good services even if they're taxed hard for the privilege of living there. See London, NYC, etc. Taxes in those places could and should be higher. A little tangential perhaps, but we don't adequately measure the value amenities and services have for people, so we disadvantage ourselves in conversations about tax.
