Except, that isn't unique to Picard at all. TNG and DS9 both had those thing-Beverly purchases a bolt of fabric in "Encounter at Farpoint." O'Brien is extremely prejudiced against Cardassians, including having a slur to describe them. Worf is highly prejudiced against Romulans, to the point of letting one die. We hear about holoaddiction, caffeine addiction and other habits.By our standards, it’s a more believable view of the future. People still have vices, they still bicker, kill, enslave, discriminate on racial grounds (treatment of Romulans), there is still money and by implication, rich and poor.
I may not like TNG but I think it had an interesting blend of humanity that is reflective in Picard. Picard just has the problems front and center rather than as a B plot.
