Well, yeah, it's a failing social system, not necessarily a failed government. I don't disagree with you, but the reason that there's no housing available is because it isn't just the government, which in Finland is also a representative democracy, nor the economy, which in Finland is as capitalist as any euro.

It's due to things like societies, cultures, and banking systems that create and foster housing and property bubbles. It's due to things like the power dynamics between the socioeconomic disparity and the difference between the wealth of the governments entities in charge of these social systems versus the influence from business, private, and banking interests from the outside. Then there's the laws where actually trying to help can make you more liable if you don't provide enough aid or are held responsible for the condition of those you are helping, a fear particularly present to many people in the US and China alike.

Finland has a small socioeconomic gap between its extreme while being one of the richest per capita in the EU, but it also has much more control over who can become citizens, prioritizing wealthy neighbors over the rest of its migrants and trying to reduce it to keep it from saturating its social systems. Not every country can adopt the same solution without massive reforms and geographical shifts. It doesn't mean that spikes in benches and under bridges are the solution.
