On the state level, any broad based benefit that does not discriminate is also futile because benefit recipients can move into the state and payers for the benefits can move out of the state.

It the same problem with homelessness, education, and mental healthcare (a subset of healthcare). Without a border to limit the ratio of net benefit recipients to net payers, the numbers will not work out.
