This is an extremely reductive take based on anecdote.
There are a lot of reasons people can feel lonely. Hell you can even feel lonely when you have deep meaningful relationships. Sometimes it’s a result of anxiety or depression, or an abusive relationship.
Of course some people fall into the category you speak of too.
This. They’re more widely pissed off at the status quo because they never had the future that millenials were tricked into believing but received scraps for. Now the scraps are all gone and gen z knows it.
Socialists like Mamdani give an actual hopeful future with a real tangible promise.
The ones who voted for trump didn’t have that at the time and were faced with forever status quo of insufficiently paid debt servitude, or try something. Even if it just breaks everything there’s at least a chance for a better future in the aftermath.
I’m not saying there’s a shortage of fascist gen z, but there is absolutely a shortage of better options in politics. I hope we see more unapologetic socialists like Mamdani. I’m happy to bet the vote would swing amongst gen Z significantly even in deep right territory.
