Let me show you that statistic in another view:
The states that are receiving the largest payments when compared to the taxpayer contribution toward federal taxes are the states that voted for Trump. For example, every $1 that South Carolina sends to the Federal Government is matched by $7.87 in Federal funds sent to South Carolina.

Why? Because these states have a larger number of the three categories of people who need the social safety net: the elderly (through Medicare, Medicaid and Social Security), children whose family is below the federal poverty level (through the Children's Health Insurance Program [CHIP] and through programs like Women, Infants and Children [WIC]) and the working poor (many of whom are in the industries worse hit by the recession and globalization).

Universal Healthcare has little to do with these programs, however. Universal Healthcare means that everyone has coverage-
particularly people who work but whose employers do not offer health insurance.
Pete Stark, a former US House member, used to give speeches at healthcare conferences. One of things that he was famous for saying was, "The only group of people who get Constitutionally guaranteed healthcare in the US are the incarcerated."
Notably, he also was famous for telling physicians to stop whining since most of them had obtained their MD from a federally-funded medical school while working at a federally funded hospital financed via federally-funded student loans. As the beneficiaries of public largess, the least that they could do was pay it forward through public service to those who were less fortunate.
