I'll address the last point first because it's so critical. WE DONT NOT WANT CALIFORNIA TO SECEDE FROM THE UNION. They pretty much are the US GDP, our produce and tech products.
But if California votes for secession, you must accept it. Or join UK again to remove illegal secession precedent.
As a moderate/progressive, although the thought of dropping some of the less productive (economically and sociopolitically speaking) makes me salivate. But, in the interest of representing the entire constituency, we have to offer equal representation despite contribution. If we are a community of equals, let all voices ring at the same volume. Representing only one class of citizen, as least as far as political ideology is concern, breeds the path for taxation without representation. And as history has proven, shit gets burned down when we get there.
I didn't told to drop them. I mean let them go if they wish, the same as UK accepted US declaration of independence.
