I can't kind think of an instance where they ever speak of present day earth.
I can't think of one either (at least not in anything past vague reference to something being from Earth or that sort of thing), but I do think they mentioned the lack of money, prejudice, poverty, war, that sort of thing, and I was including the whole STU, and TNG and DS9 definitely make mention of it (DS9:The Maquis, pt 2: SISKO: On Earth there is no poverty, no crime, no war. You look out the window of Starfleet headquarters and you see paradise. I was just watching that so that's why that one came right to mind, but I recall Picard saying the same kind of thing too, a few times iirc).
But in I don't see Kirk arbitrarily deciding the culture has stagnated and going in aiming to wreck it (not in The Apple nor other TOS episodes). I see him either being confronted by a danger posed to him/his crew/his ship (as in The Apple, the ship was being drained of energy etc), or by an aspect of that civilization that is in fact at odds with their portrayal of perfection (also in The Apple, as the populace were in fact slaves to Vaal, an "alien" machine). We could debate on how acceptable his judgement of other cultures based on human perspectives of "right and wrong" are, but I bet we agree that when it poses a danger to his crew/ship, there's a justification on his part for what he's doing. They always seemed to like/admire/appreciate apparent "perfection," until they discovered some "fatal" flaw (that endangered them).
Unicorns have the right to exist, that doesn't mean there are unicorns.
There are plenty of unicorns. Unicorns are imaginary. (Imaginary) Unicorns "exist" all over the place (Charlie the unicorn anyone? ;-)). No one said imaginary unicorns have a right to exist as real creatures. They most certainly do not... not unless we are going to do something about those horns of theirs ;-).
Lazy people on the other hand, are (arguably) a (minority) cultural group, and should be protected! SAVE THE BUMS!!! I mean, we're trying to save the whales and dolphins... and I hear dolphins at least spend most of their time playing (the assholes).

Prior to "getting rid of" those people, you could simply label any people who you disagree with with those (or other) terms, this of course would make it easier to "getting rid of" them. Can't have people you disagree with having any say in societies decisions.
Maybe not.
Well let's define "getting rid of": If we as a society are (purportedly trying to) teaching our new generations to be progressively less bigoted, we are "getting rid of those people." Is that ok? I mean, that's just how society works. I am hardly advocating "lining them up against the wall and shooting them."
I've always had a weird thing about that whole concept: not allowing fascists or racists their opinions is fascist (and racist, if everyone else can have their opinions, many of which are racist too). Of course them running around lynching people isn't ok either... so where's the line?
