You may not be on an ACA plan, but many forum members here are (check the number of threads on the topic), and none that I have read about are on food stamps. Since your audience for this thread is presumably forum members here, I think many have benefited from affordable health care costs with the ACA. Those with MAGIs below 400% of poverty level may receive tax credits. Before the ACA many of us could not obtain health insurances as seniors at any price.
Now many more people at higher income levels qualify, up to almost $300K MAGI, assuming $25K premium costs for a senior couple. From what I have read, this would be over 98.5% of households now qualifying. "The American Rescue Plan bolsters the availability of premium tax credits (PTCs) for millions of lower- and middle-income people and families. First, individuals whose income is above 400 percent of the federal poverty level (FPL) are eligible for PTCs for the first time.
There is no upper income limit on PTCs, meaning that all middle- and upper-income individuals who purchase their own coverage can access PTCs if their premiums exceed 8.5 percent of their overall household income."
