Unfortunately, one of the proposed solutions — the amicable split — is impossible, because the Left knows there is no “them” without “our” money, labor and resources.
Don't be so sure. I think many on the left would view North Korea as the ideal... where ALL live in equal misery. They might welcome the opportunity to implement their plans in their portion of the country where they won't have people fighting back against them.
“They” would still have the wealthy tax payers of NY, CA, MA, CT, etc., at least until they flee to the seceded states.
