Science cannot be bought in the store, you don't have a market of people willing to pay you back. Its not constantly craved by humans unlike entertainment. And it is not limited to general rules of business, specially when we are going beyond our abilities, and stretching them even further. For example, ISRO have never had a engine before that could re-ignite after a 300 days period of cryogenic conditions of space. That technology developed in extreme conditions can be reverse engineered to make our cars perform better in winters. Or some other applications. Does that sort of returns even get reported ever?
