It's much harder to get large swaths of the public addicted to opioids due to pesky red tape from Brussels. And there are far fewer veterans you can abandon to their battle PTSD in tent camps.
I read about a Finnish initiative to just get everyone they could find on the streets of Helsinki without an abode into apartments, give them money, and help them sort out their lives and get them into jobs wherever possible. That's socialism bordering on communism to American ears. That's quite lefty even by European standards, sadly.
In America's defense it's easier to do in a country of 5 million people than in one of 340 million. That's not a reason not to try though.
I see your bullshit and raise you horse manure. Speaking from an administrative point out view, it is indeed harder to run a program like that spread out over a much larger area with a much larger population to deal with. A complication in the US is also in differing state laws. This probably wouldn't work EU-wide either.
Also Finland didn't start from a large pool of homeless people due to mental illness or medical bankruptcies because there were other social safety nets spun before this one to catch a lot of the people before they became homeless.
Blame the US for not trying. I do too. But "economies of scale" are not going to help a program that for it to run well cannot be run like a business.
