Earlier quoted context omitted.
There's a lot to nitpick here but I guess the most interesting thing to me is that, for all their wealth, access and smarts, none of these people seem to actually be trying to solve the systematic and endemic problems which would soften the blow of a major existential risk. When the best and brightest of a society are heading for the hills, that's a sign problems are coming. It's not that just they may have concrete…
You could also ask the question what they are protecting themselves from. Maybe they expect at some point that the masses will no longer want to keep paying taxes an lose money, while the rich have all the means to circumvent taxes and leverage their wealth. I don't see the breaking point yet, but there is definitely a breaking point.
and did you know that the bottom 50% paid 2.75%?
would dropping that 2.75% down to zero (which sounds fine to me) avert the breaking point?
