Portland (population 622k) spent $531 million (https://www.koin.com/news/portland/shocking-amount-spent-on-...) which is 1/16 of the $8 billion that will fix homelessness according to you.

By your reckoning, Portland, which is 0.15% of the American population should have been able to fix homelessness for its entire population for $12 million. Portland spent 45 times that so we ought to be able to house the homeless in the Ritz Carlton, if your calculations are correct.

But they're obviously not. And your argument is childish.
