What data (if any) would be sufficient to convince you that inequality is not a problem?
Other measures of the social ills correlated with being very poor? In cities, if you are also black or hispanic , a high chance of death by violence. A relatedly high rate of incarceration, often for nonviolent crimes. High rates of children in the foster system.
Just because the averages nationwide are slowly ticking up over time, does not mean that there are not significant populations slipping backwards.

Do you believe that if the 1% had less money, poor blacks/hispanics would be less likely to kill other poor blacks/hispanics? If not, this is irrelevant.
I haven't double checked this, but I strongly suspect that even as inequality has risen in the US, the rate of poor blacks being murdered has gone down. (Reason: poor blacks being murdered is a big chunk of the murder rate, and murders and other crime have generally gone down.)
In general, poor populations have reduced access to high-quality care. While people with low incomes are more likely to be uninsured, income-related differences in quality of care that are independent of health insurance coverage have also been demonstrated (Brown, et al., 2003).
Also this metric has increased over the years:
People without a usual source of care who indicated a financial or insurance reason for not having a source of care.
