Why are there so many youtube channels where australians with STEM degrees do science and engineering in dangerous and irresponsible ways? Do they not have anything better to do down there besides sports gambling?

florida has the same problem but thats cause its swamp land ruled over by amusement park cabals and retirement communities, so it makes sense that there is nothing to really do down there besides seek an early death. Australia is supposedly a functional country but their cultural output makes me wonder.
we made good movies and tv from the 70s to the 90s, then the powers that be decided it'd be better to make suburban white people drama, dystopian reality tv, and family friendly comedies about dogs. just collectively deciding we'd rather have the cultural output of Francoist Spain.
All the STEM jobs are in coal mining conglomerates so the PhDs of Australia would rather just fuck around in their backyards and play the youtube lottery
