There’s an enormous difference between millionaires and billionaires, and any piece that mentions them in the same context should automatically be disqualified as pro-hyperwealth propaganda. A billionaire could give up 5% or 10% or 90% of their wealth and see zero material difference in any aspect of their life - they’d still be unimaginably wealthy by any standard. It’s just keeping score at that stage.
The people leaving California because of the proposed billionaires’ tax - which will never happen btw - are selfish whiny crybabies who should be ostracized from public life. Good riddance to them.
