This is already happening in CA and will in Florida and Texas if they don't stop their accommodation of any immigrant that shows up on their doorsteps.
At some point in this scenario, one would hope that the citizens of those once great states will blame the leftist Democrats that created the downfall and boot them out of office, choosing conservatives to get the fiscal house in order. Then the cycle will repeat itself again.
Or they can just keep spending & ignore the deficits, as some states are doing.
