I'll go with "never".
Technologically, some things depicted in Star Trek just aren't possible. All the evidence suggests that faster than light travel is among them.
Ditto for the social angle. Crappy jobs will still need to be done and, by and large, people aren't going to do them unless they have to. That means money isn't going anywhere.
I don't mean to sound overly pessimistic. Sure these things could improve. They just won't improve in the direction Star Trek depicts.
