I work in cancer research in the UK, and ALL our money is coming from the government. Where there's a will and relevant priorities, there's a way. That's really the crucial part, because governments have plenty of money to spend. Where they spend it is the real question, not how to raise more.

That said, even just moving the extracted profit into taxes instead would yield a substantial improvement. People make money off of this. Stop that and move the money back into research.
