Today's youth grew up with the dotcom bubble, financial crisis, 9/11, and COVID. They're far poorer with less opportunity than prior generations had. The government has failed them and they want change.
This is pushing younger generations hard left, and I don't think it's going to change. Most of the "conservativizing" life events like home ownership and building a family are being delayed or just never happening. Today's mellenials and gen z will likely lean democrat till they die.
There's also a social theory that older generations lean conservative because the conservative movement dominated their youth, not because they became that way with age. Today's boomers grew up during a ~20 year streak of conservative dominance. Today's youth are the opposite, it's yet to be seen what this will do to political beliefs.
