Why do you include Social Security in the list of things that won't be eliminated? I'm not American but in my understanding UBI would almost completely eliminate Social Security, along with putting a big dent in the need for Medicare and Medicaid.

At least in Andrew Yang's version of UBI, Social Security retirement benefits would stack on top of UBI and not be replaced.

I don't think anyone has seriously suggested replacing Medicare with UBI, as replacement health insurance premiums for people 65+ would almost certainly be a multiple of $1K/mo.
