Your barrier argument sounds reasonable, but the evidence shows payments don't reliably remove the barrier that matters most: skepticism. California spent over $100 million on lotteries and gift cards, and vaccination rates barely moved relative to other states. The people who stayed unvaccinated weren't weighing lost wages; they were weighing trust. And payment actively damages that trust by implying the shot needs a bribe. If the goal is compensating real costs like childcare, that's a separate, means-tested policy. As a broad public health tool, the data says it fails, and it leaves deeper suspicion in its wake.
