Given that it's actually a relatively small number of people who fuck it up for everyone else, but often they're the ones who end up in charge, and/or who the people in charge pander to because they're pretty easy to sway and so mean near-guaranteed votes (enough to swing crucial ballots when the more reasonable bunch are tied 50-50) and sales (explaining the seeming popularity of some extremely stupid things - given the great diversity of what's actually on offer, it only takes a very small proportion all swinging the same way these days to produce a seeming market dominance)... as well as crimes, wars, road accidents, antisocial nuisance, irritating celebrity bullshit, fucked up healthcare/ transport/energy systems, terrible cases of ethnic cruelty and retribution and power-politics, religious fanaticism, general bigotry, etc...

...well, 5% would probably be excessive. I'd be tempted to go full Roman punishment / avenging angel and crank it up to 10 just to make absolutely sure, but that would probably be a bit unfair and OTT. The world needs some dissent and variety of thought, and when you get down to it *actual* right wing sympathy is naught but believing in a particular ideologically driven financial system that's about as valid as an extreme left wing one, and both arguably even equal with a centrist view. Everything else that's hung on top of them is propagandist association and even self-labelling of certain fucktards who think they're standing for something entirely different to what they actually are. Quite often there's a strong thread of authoritarianism, which is actually an entirely separate thing from your bias left or right and can be found at an oppressive level in regiemes that otherwise fall anywhere on that spectrum.

So... hmm. Just "the 1%" might not cover it. Though that's still sixty million lives snuffed out at once... even if they're all total assholes who wouldn't hesitate to hit the button set at 99% if they thought they and their friends would still be spared. Maybe somewhere in the 3-4% range would suffice, not end up wiping out any complete countries or demographics (no matter where you live or what race/creed/etc, you can still be a perfectly fine person, or an utter prick), not leading to social care or industrial / safety / food supply crises, etc. Might be a few political power vacuums, but with any luck the people who'll end up filling them won't be as bad as those who went before, thanks to the effect of the button. It might not even be entirely noticed if the effect is staggered, or some other catastrophe is in play.

Question is, does it have any unexpected side effects? Like the typical mischeivous genie who twists your wishes around? Also, does it take effect instantly, or is there some delay on it, maybe a few hours? Such as e.g. anyone in charge of a vehicle (car, bus, train, plane, ship...), or were responsible for safety critical systems and tasks, or caring for more innocent vulnerable people, that somehow fit the bill (I'd expect the largest group out of all those would be car drivers and maybe some cyclists and motorcyclists... but there are a few very bad care workers who are only in it to keep the benefits department off their back) wouldn't drop dead straight away, but start to feel a bit ill, and be able to hand over the reins, or park up, issue a mayday, etc and not feel up to trying to resume their duties (the likely mindset caught up in it wouldn't be too bothered anyway) before finally keeling over?

The phenomenon would probably be noticed eventually even if it was spread out over an entire year, but the panic would be less than if it happened at the same moment or within the same day (e.g. at either solar noon or midnight, as the sun swept by overhead, or around the other side of the world), and in fact probably be more of a running joke (like all the celebrity deaths in 2016... who knows if that might have been something similar?) than anything taken seriously for quite some time. By which point some societal shift would already be happening.

No idea of course if I would be taken by it. I would hope no family or friends, but that's just as impossible to tell. I've lost a few to the usual everyday causes already anyway, and death comes to us all in the end, so the pain is the same, just differently timed.

One hopes that the world after wouldn't seem too much different... just... less assholey. No longer going down the seemingly self destructive and conflicted path it's on at the moment, instead gradually but noticeably changing course...
