You didn't mention why you think this is a good idea or good for people.
Ari fails to mention or take into account inflation. There will be inflation between now and 2027. Assuming 3% inflation that 384 billion would be 510 billion in 2026. Health care costs have been increasing at well beyond inflation too. They tend to go up 6-7% annually. At 7% to be able to pay for the same services as that original 384 billion it would take 719 billion.
What is your expectation on how that monetary shortfall will be made up? I suspect it will be to cut services. I don't see the value in cutting medical services to the poor in order to fund tax cuts for millionaires.
