what do you think the money is for
- Manpower requires having people who actually want to work for whatever organisation and have the necessary skills to perform the tasks necessary. In terms of diseases, that requires people who are qualified in specific scientific fields, or it requires engineers capable of creating any new tech necessary to study the problem and create a solution. People in those fields aren't in abundance.
- Time can't be bought.
- Physical Resources are not always available with money. Asking for technology we don't have which is out of reach or for very rare materials can't be done on money alone.
