Lowering the financial barrier to entry would help. Idk how, but part of the industry's problem is that people who want to learn to fly can't afford to.
I've seen rich people take it extremely seriously and with great attention to detail and safety, just the same as I've seen people who struggle to get the money together to go flying do the same.
I've also seen a lot of rich, successful, type-A people just not have the mindset of "Oh shit, this could easily kill me" because they've been successful at some other aspect of life.
