I have never heard of a scientific conference with a $5000 prize. Was it a private fundraising conference? Perhaps it was private clinicians? Scientific research conferences are far more austere, but conferences for medical doctors are often like that (they do not usually get paid out of grants).
What you are describing is not normal. Please name the conference and shame it.

Oh no, should we not have this? Do you really want to say this should not be happening?
Having conferences in Las Vegas, San Francisco, Newport, NYC, Miami, Boston, Chicago, Austin, is all normal. That is not wasteful. That is the necessary spread of ideas in science.
If your wife cannot understand why the data is not presented over Zoom than she is missing the primary purpose of these conferences which is meeting with lots of people in a short time to establish collaborations, chance encounters with new ideas and people, and other things that are not possible over Zoom. Perhaps she should stop wasting money by attending them and let others attend if she finds them wasteful.
Your representation of science is not the representation that I commonly see, and seems mostly to exist to discredit science. It seems that your intentions are more political rather than to accurately inform about the situation.
