Income is lower but actually taxes are fairly similar in the lower income brackets thanks to progressive taxation (and I'm not too concerned about the top earners starving). Buying a home in Helsinki – which is the only place in Finland where real estate prices are actually a problem – takes about 9 year median income, quite similar to cities in the US. Outside the Helsinki metropolitan area real estate prices are not bad at all. Either way if you're top 5% income you can easily afford to buy a house.
> of course you probably mean the technical "affordable housing" definition which just means housing for anyone making under median area income. the money to fund these things comes from somewhere, and it seems to typically always be the middle class.
Abundance of apartments affects prices for everyone including the middle class. The only ones not benefiting from affordable housing are (literal) rent-seekers, the people and companies owning real estate purely as an investment.
