First, if we knew for a fact that at least one apparently incredibly-abled UFO sighting in last century was really incredible and not from a then-current human Earth power, it would make sense to spend ~1.0% of world income, or ~$1.2T/yr, on researching and studying UFOs.

Second, the actual median estimate chance of that fact is ~1.3x10^-5. So if the best amount to spend on UFOs were proportional to this chance, that would imply ~$15M/yr UFO spending, which is at the low end of the ~$20-50M/yr that five LLMs estimate the world actually spends. Third, poll median best spending on UFOs is ~$65M/yr, near the high end of that range. So polls roughly endorse the status quo.
