This is manifestly untrue in so many domains, including medicine. Most research is heavily government funded, particularly pure research, and most academics are not interested in profit. The only orgs motivated by profit (drug companies, insurance companies) are the ones who push this misconception, because they profit from it. As one example, the UK runs large trials comstantly to improve care, without a profit motive.
