DoD spent $1.43 trillion in FY2026

Around ~1 million homeless in US

Let’s say it costs $10K/month/person so $120K/yr/person. Probably a big overestimate but gotta include healthcare and help people with long term stability.

That’s 120,000 x 1,000,000 = 120,000,000,000 or $120 billion USD.

Idk what the Nth order effects would be but yea I think what you’re saying tracks in the numbers

For an ideal ('spherical cow in a vacuum') type of homeless person, sure.

You cannot just throw money at a problem like homelessness in order to fix it. That is such an incredibly reductive viewpoint. It's akin to saying 9 mothers can birth a child in a month - oh look, we solved the population decline crisis! Someone go tell Japan!
