>>The scale of social problems in the US is on a whole other level. More people requires bigger solutions.
Bigger country also has far more available resources.
From TFA:
>>So, more than a decade after the launch of the “Housing First” policy, 80 per cent of Finland’s homeless are doing well, still living in the housing they’d been provided with — but now paying the rent on their own.
>>This not only helps the homeless, it turns out to be cheaper.
That bears repeating: it turns out to be cheaper
The solution can be found in the common refrain of conservative ideologues fighting against social programs —— it isn't the government that knows how to best spend the money, it is the people.
The really simple solution to homelessness and poverty is:
Literally house the homeless and give UBI to everyone at a poverty level.
It turns out that the individual people really often do know how to pull themselves up by their bootstraps, as long as they have bootstraps.
A tiny house with a fixed address, bed, toilet, shower, and cooktop eliminates enormous classes of problems both for the unfortunate people, and the rest of society. A basic income is most commonly used by people to improve themselves. Yes, there will always be sad examples of people who fail and use it to drink/drug themselves to death, but every actual study I've read shows that these are vastly outnumbered by those who use the minimal resources to get out of their personal hell; this is just another in those long series of studies.
And to those who scream "moral hazard - you're rewarding bad behavior! Welfare queens!!" — bullsh^t. The richest societies in the world can afford to provide basic housing, food, and medical care to all their residents (but not the entire world, immigration controls are needed). No one wants to be in the dregs of homelessness and poverty. And, the objective results are better outcomes, more people overcoming their problems and becoming self-supporting.
