Using typical Rat mentality, they will probably try to make up the difference by raising taxes on the 2/3 who have not fled.
They've been doing it through the years.. and LOOK!! It's turned out SO well!!!! /s
No, the Democrat Liberal Elites will retroactively charge these rich scoflaws an exit tax that will correct the revenue imbalance. The last thing California will do is to charge illegal mexicans more taxes; they are not for taxes - they are for voting Democrat, period.
It is up to these rich refugees to tell California to go f@ck itself when the state-contracted debt collectors come calling.
