Sorry to add the depressing side but we have been protesting the rising costs of housing for decades and nothing seems to be improving. The slogan "You aren't going to own a house in your whole fucking life" is almost 20 years old now.
We, like the Americans, keep voting right for fear of the job stealing immigrants, and then the centre-right for fear of the right steering further right ("useful vote" they call it).
I left more that 10 years ago, though. We managed to put the left in the government in the meantime, in exchange for their support to the centre-right. I don't know how are they doing, but if there are still protests my guess is there hasn't been a lot of improvement.
I'm too dumb to understand economy but the problem seems global and above a single country's agency.
I won't die on this hill tho, I haven't pit much thougjt into my comment.
