I mean, plenty of Gen Z end up on the streets too, just like any generation, because housing availability and income is just getting worse for poor people. Anxiety issues are fairly associated with poverty.

Most the young people I know (California, USA, I'm a young millennial) are precarious, and most feel precarious. They are also watching baby boomers (sometimes their parents and grandparents) end up on the streets in high numbers, but also don't have the extra income to put into retirement or get a healthy savings to secure a future for themselves, much less help their ailing family members. Their health issue incidence is high, and the availability of care for those health issues is low and very expensive. People living off of Gig apps and part time jobs (because jobs with benefits are unavailable without a college education, and sometimes even with). If they live separate from their family most of their income goes to rent.

And climate change isn't something that affects people 100 years from now, it affects us right now in certain zones. The number of homes destroyed/damaged in various disasters each year where I live has gone way up, and a lot of the people who are displaced end up on the streets or in ever growing slums/camps. There's a general sense that the future will be worse than the present, which makes present struggles feel worse. People turn to drug use, sometimes to self medicate for physical and emotional issues. People don't want to have kids, because they don't see a future for those children, and don't have the resources to provide for them.

I agree there needs to be more solidarity, especially with the most impoverished. Part of the struggle is worsened by atomization and individualism, and propaganda deriding the impoverished.
