He was homeless because his family came over as refugees. That’s uniquely American because, for the most part, the rest of the developed world hasn’t accepted refugees and economic migrants at the rates the US has taken them. (Very recently that’s changed in places like Sweden, but it’s already causing those countries to go into right-wing coniptions.)

But this kid was in a homeless shelter. That’s how most countries, including Sweden, house their homeless population. (Fun fact, rates of homelessness are lower in the US than in Germany, Sweden, or the UK.) It’s not like you show up to say Germany as a refugee and they put you in an apartment. (There are 400,000 homeless refugees in Germany, comprising half of Germany’s homeless population.) You stay in a camp for a period, than are transferred to the municipal housing assistance programs, which in Germany are a bit more generous than Section 8, but not fundamentally dissimilar (being structured as subsidy where the state pays part of the rent).
