Earlier quoted context omitted.
I’m Finnish too. My entirely anecdotal experience of both Finland and USA is that America is about 40 years behind in responding to poverty. To see men sleeping in trash boxes in freezing weather, you only need to walk a few blocks around midtown Manhattan in the winter.
The USA has a lot of room to improve for sure. But solutions that work for Finland, which is a small, ethnically homogeneous, high trust society, simply won't map to the USA which is the opposite of all those things.
To finance it, tax the rich, dismantle 4/5ths of the US military and stop fueling wars overseas.
But that's called socialism and is (unlike actual treason) treated like it would be high treason by the US political parties; mostly because they are all in the pockets of wealthy donors who would not like this new regime.
