how this is different from what has already been in place.
My Mother-in-law was an Alzheimer's patient in a nursing home for 14 years. When she died (mercifully) all of her remaining assets were turned over to the State through the program.
She went through her life savings and the meager amount she received from the sale of her home and assets within 18 months and became pretty much a "ward of the state". Her Social Security check was sent to the State every month and she was allowed to keep $75.00 per month of it for having her hair done, replacement clothing or newspapers or other treats (within two years she was beyond reading and treats).
There were frequent accidents and crisis' but most of those costs were covered by medicare or medicaid depending on the situation.
In short there was no prevention of impoverishment then and it looks like there isn't now either. I suspect we will see more TRUST accounts set up to shield assets from these laws but they have been used extensively in the past too.
Nursing homes are the greatest TRANSFER OF WEALTH vehicle ever invented. Nobody seems to notice that.
