Food assistance, aid to dependent parents, housing assistance, just generally whatever is available by way of what is commonly called "welfare".
I was aware of a case in my own district of a man who was impregnating his own intellectually disabled daughter for the income. She may have had previous babies that ended up being dumpstered before the final one was caught by a very astute ob-gyn who had dna tests done that verified the parentage of the baby as incestuous.
He basically was running a baby-mill. The poor daughter didnt even own a toothbrush and had to be shown how to use it in the medical clinic and also given showers before her appointments as she was never bathed. She may well have eventually been dumpstered herself after her emergency hysterectomy made her unable to reproduce again.
The things I saw in those mountains and in social services have been lifetime traumatizing though that was a lifetime ago.
