I know of a number of people who worked their entire life, then acquired a catastrophic illness and could not work. They then ran out of insurance money and retirement savings and had to go onto medicaid so they could live in a public nursing home until they died. Someday it may happen to you. Just as with any govt program, there are those in real need and then there are a bunch of others like illegal immigrants who are taking advantage of the system.
And I know of a number of cases where those people worked to transfer assets before applying for Medicaid to shield their heirs’ inheritance. We got stuck with the bill.
