But your description of the typical USA based couple "quickly spending down their assets to nothing" might not be all that true for the FIRE types here. For example, like DW and I, many have planned to self-insure
Exactly. DH and I will be self-insuring for possible long-term care expenses.
We will have Medicare, of course, but my husband was a federal employee, and we have a Blue Cross/Blue Shield plan with his retirement. Whenever we travel internationally we are told that we are covered for healthcare, just go to where we need to go for medical care and we'll be reimbursed by BC/BS. I don't know if that is supposed to be used solely in emergency situations. We have never had to do it, and now I wonder, if we were to live at an assisted living place in Mexico, if our BC plan could be used consistently for medical care and prescriptions.
