It's surprising how shamelessly they are doing it. I would have expected more sophistry.
I would say that is fairly accurate.
I've noticed that when it comes to Adam Smith there's no shortage of people who try to make out he was some kind of proto-communist while smugly telling off straw man economists for cherry picking him - but it doesn't seem true to me.
"It is not very unreasonable that the rich should contribute to the public expense, not only in proportion to their revenue but something more than in that proportion."

People are naturally self interested, and enabling them to voluntarily trade with others as they see fit enhances the life of each partner of the trade. Scale that up and society advances itself with an centralized arbiter to guide it.
As for taxes, the reason he felt that the rich should pay more is because they derive the most benefit from the existence of the state.
