What is the government’s role in financing healthcare systems and public or private insurance in the United States versus the industrialized county that you selected?

Compare the United States’ healthcare system with another industrialized country (e.g. Canada, Japan, Taiwan, etc.). What is the government’s role in financing healthcare systems and public or private insurance in the United States versus the industrialized county that you selected?
Medicaid was created as an entitlement program while CHIP was established as a block grant. Should one program be changed to be either entitlement or block grant so that both are financed in the same way? Provide your rationale with supportive literature.
