Personally I agree with the logic that if we have the choice between 0 and 100,000 people living for ever we pick 100,000 (Even if that 100,000 include such greats as Un and Assad). Having said that If I had the choice between 100,000 living forever and 3 billion people living forever with less private jets in the world I'd pick the later. Perhaps I'm cynical but if we do indeed get this tech I'm a lot less confident about my values being satisfied in the second instance than the first.

But I wouldn't argue with you that the majority of these 'elite trimmings' set the society back. The question is after the set back does it move forward faster than it was or in a better direction (Often the answer to this would be hugely reliant on your personal values).

Not unless they're going to be benevolent rulers, no.

I will not grant people immortal life so that they can make everyone else's lives into a living hell.

We eradicated smallpox for everyone, without distinction between rulers and ruled. That's the difference!

You may want to familiarize yourself with the history of smallpox eradication before continuing this debate. The vaccination was available mostly in wealthy countries first.

http://en.wikipedia.org/wiki/Smallpox#Eradication

"...coordinated efforts against smallpox went on, and the disease continued to diminish in the wealthy countries. By 1897, smallpox had largely been eliminated from the United States.[66] In Northern Europe a number of countries had eliminated smallpox by 1900, and by 1914, the incidence in most industrialized countries had decreased to comparatively low levels..."

Notwithstanding the daughter comment that disproves this, try substituting 'smallpox' for 'cancer'. Cancer treatment is by no means available to everyone, or even the majority, yet it extends lifespans (of good people and dictators alike). Should we not have developed treatments for cancer?
