HSAs only benefit the people who can take advantage of them. Upper middle class and the wealthy.
Your side loves pushing the idea of HSAs connected to high-deductible catastrophic insurance policies. If someone has a $10,000 deductible and has a major illness or requires surgery, and they can't pay the $10,000 deductible, then what? All the tax deductions in the world won't help them if they don't have that $10,000.
