Where are the families? My mother-in-law was in a nursing home for the last several years of her life. She did not receive Medicaid. It cost $5,000 a month and exhausted my in law's savings. How many families can afford to pay $5,000 a month for nursing home care? 
As for it being a "personal choice" to have a low income job without health care benefits, not everyone has the education, training, capabilities, or skills to find better paying work. And sometimes the jobs are not available, even for those who qualify.
