I don't think the outer planets (Uranus, Neptune, Pluto) have any dignitaries, exaltation, and fallen positions. They each last a very long time in each sign and spend the majority of the time in retrograde. That being said, Pluto is the furthermost planet and stays in a sign for what? 15 years or so? YIKES. That means that for a good 15 years everyone born in a "fallen" sign are part of a busted generation and everyone born in an exalted sign are part of an awesome generation? NO, that's wayyy too broad of a scope.
The outer planets don't seem to lose any power no matter what sign. Either way, they still have the ability to influence events in whatever flavor sign it's in.
I'm part of the tail end of the Pluto Libra generation which means it spanned from roughly 1971 to 1984 and it's been speculated that this particular Pluto generation will "bring marriage back" by the time we're in power. Umm... by the time the Libra Pluto generation is in power, that means we'll be in our 50s and 60s and by then, we ourselves would probably all be married or at least married once. How the heck can my Pluto generation bring marriage back? LOL We'd all be so old that the younger generations would think we're out of touch with reality! Right now, the Libra generation is actually REBELLING against marriage and have opted for live-in partners, not having kids, and furthering their career. So I'm wondering, those born in the Scorpio Pluto generation... when they're in power, does that mean super weird/creepy sex acts will become the norm?
In response to,
"If you have Pluto close to an angle, then he becomes even stronger, and he is also strong in the 5th, 7th and 9th houses. So if you have Pluto rising in Libra or Sagittarius, and to a slightly lesser extent Leo, then know that you have quite a trip ahead of you and you need, for the sake of your eternal soul, to get down to some serious spiritual work if you want to avoid the burden of a lot of karmic payback......"
I don't quite understand why Pluto is particularly "strong" in the 5th, 7th, and 9th unless you mean it's powerfully malefic in those houses. I don't know about Libra Pluto rising but I do have Libra Pluto in the 1st house and I can say that I've had a really "long journey" with no end in sight but I wouldn't say I've encountered events and people on a karmic level. But then again, many people can say that without having Libra Pluto rising. What makes it so particular about Libra Pluto rising has to be the one with karmic baggages?
