Homed by a process that the United States also doesn't have and would need. It would be dishonest to compare the rates without including the cases that Finland has already solved through a similar (but not as far reaching) program.
No, I think it's perfectly honest to compare the rates of homelessness in a country that has worked to improve the situation versus a country that continues to let people die in the streets. It seems far more dishonest to compare the rates before the work was done, considering that work was done to reduce the problem. The reason that the US now has a roughly 5x rate of homelessness (and, let's face it, growing) vs a roughly 1.3x rate of homelessness is because the United States has no interest in fixing the problem.
They've been homed, but subsidies for the housing of previously homeless people are typically aggregated under homeless spending. (The US has a lot of programs like that as well.)
