There is absolutely nothing preventing the government or non-profit organizations from developing drugs and selling them at a lower price. Nor is there any reason we can't implement some system to help subsidize people who can't afford health care. Patents are not the issue at all. Without patents the people who die because they can't afford health care would still be dead. But so would everyone else who was saved by the drug, which includes those people in other countries you mention, and people who benefit a decade later after the patent expires.
