My understanding is that these idiots are talking about putting both education and pension expenses on towns that “can afford it”. What happens when people want out of those towns and no one wants to purchase their homes? Won’t lower property values decrease property tax revenue? CT is already losing relatively wealthy retirees and others who have had it.
That is also happening in NJ, and in response to your question: Some people outright abandon the homes, while others find some “replacement Americans” as tenants until they can sell it.
