You have never been to the Netherlands, have you? Because those statistics you hint at are misleading at best.
Means for the slightly-better-off middle class to exploit the lower class through rent are being thwarted, thankfully. They just allow one half of the population to exploit the other half without providing any tangible benefit in return.
Source: I'm born in, and living in, the Netherlands.
I actually lived there for a period, not that it's relevant.
How does merely visiting Netherlands tell a person that inequality stats are misleading ?
