Of course the New Republic is better than the Empire but the upper class in Coruscant and the working class in the Outer Rim haven’t been made to notice. Nothing substantial has changed about their lives. The status quo is too strong. The New Republic hasn’t done enough to rid the galaxy of the Empire. Things aren’t improving enough.
In order to more rapidly rid the Galaxy of Imperial leftovers, it would help if the New Republic didn’t throw away all their military hardware for no reason. At this point in history, I would expect the New Republic to be very fragile, but in the new canon it seems like the Battle of Endor (or maybe the follow-up battle at Rey’s planet) was supposed to be this ultimate overnight decisive victory. (I forgot a lot of these details - but I remember also there was something about Palpatine being insane and having this automatic protocol that purposely sabotages the Empire in the event of his death.)
