There are ample government and private support mechanisms, including housing and food, but most choose not to take advantage.
You don't need private people/companies or more taxes for that. US has enough resources to do it already. Maybe you should go ask your politicians, better yet, ask your friends/neighbors/yourself if you are ready to take the drastic steps necessary to solve that.
But imagine engineering hearts so that we did not have to ask?
If govt really cared about it, more than that, if (most) PEOPLE really cared about it, it should be top 3 priority of any govt in any country.
- Govt should build massive cheap hotel-type housing spaces (full free) equipped with bare minimum necessities like roof, heating, food, basic healthcare (not million $ free cancer treatment).
- Mandatory drug rehabilitation (if applicable)
- Mandatory job search/placement/training
- Jail with forced-labor for people who put no effort and/or causes disturbance
If your govt has $6M to fund tourism in Egypt, money to fund opera/ in columbia, comic book in peru, then they have money to help homeless people IN the country. No money should go to non-citizens (let alone non-citizens in another country) while citizens of a country go homeless.
I am typing this from the security of my home, without worrying about 0c temp, or food. So it is easy for me to say this but still, I am sorry that you are going through this, and I sincerely wish you the best; that your life turns around, even if just a little, enough to have a roof over your head.
I grew up reading Zubrin's The Case for Mars, The Martian, and October Sky. I went to space camp at NASA, and as a 14 year old I sent an angry email to NASA when I learned of the early ISS decommission date(they later extended the lifespan several times, and I like to think I was the reason ;) ).
I followed Bigelow Aerospace in the 2000s doing the only interesting commercial work in space, and afterwards became amongst the first online SpaceX fanboys, long before they ever landed a merlin engine.
I studied hard in school with a passion of going to Embry-Riddle to learn to build rockets - though I ultimately chose a software path in life instead, I stayed an enormous space fanboy over the 2010s, frequenting the SpaceX subreddit and catching every launch and landing stream I could live.
I've cried watching so many rocket landings. The spirit of human endeavor is god damn BEAUTIFUL to me.
I want to point my finger and say that everything else changed. The Internet became what it is. Elon Musk showed his true colors. Software Engineering became middle management.
But the truth is that I've changed.
I care about the people wealth disparity hurts more than I do about us getting our perfect vision of the future now now NOW.
The faster we pump this machine, the louder the Earth is SCREAMING.
The world is on fire, and we're covering it in data centers with the goal of building artificial machines for strip-mining humanity of the very competency in engineering that has given us so much joy.
We're caught up in a race to the bottom and without diverting our path I have to wonder if this starship landing will be one of the last great human-driven engineering achievements before we lose the ability to do so ourselves.
I don't think the answer is to swap the passion for engineering with compassion, as I think they can both live happily together, but I hear where that desire is coming from.
It's coming from a place of love.
And when the last tree has fallen, we may find that we cannot eat money.
May love fill this place.
Musk's Neuralink is ironically likely to help on the psychiatric disorder side.
Just Send More Money™ is not likely to help (as you recognize). Neither is "compassion".
