Harvard study reveals taxing job-based health benefits would hit working families hardest

A new Harvard study finds that taxing employer-sponsored health insurance would disproportionately affect low-income families, taking up to 18.3% of their income, while high-income families face only a 2.7% tax rate. Single-payer national health insurance is proposed as a more affordable option for universal coverage.
