I had reviewed programs where people on 200% of defined poverty level can access Medicaid with a small premium. You're right, for $50K you'd need between 3 and 5 kids to meet that definition depending where you live.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
