But why wouldn't disenchantment towards the rat race lead us more towards a "I'm just not going to play the game and enjoy myself doing art or whatever" rather than a "maybe the current conflicts will explode spectacularly and destroy the status quo" mindset?

As mentioned, this seems to be more prevalent in people who are, objectively, well-off in the financial department, so it's not like they "hate" the system per se and could afford degrees of financial independence that many others will never be allowed to.
