This is a real issue in my community (as is the case of pretty much every community). All the older homeowners and younger/middle aged middle class yuppies love to talk about how they care for the housing crisis for us poorer youth, but then anytime a plan to address it comes up it's all "muh property values, muh investment". It should be obvious to anyone that for the price to go down for buyers, the sellers must sell for less but they all want to sell absurdly high and then buy another home for low.
There’s a very clear way to fix this in an instant.
Give people money equal to the reduction in home value. And/or a debt jubilee.
That’s it. Easy. Done.
A debt jubilee will just pay off your landlord's mortgage
Not if we channel Mao Zedong's brilliant solution to that problem first! Not realistic right now, but if we ever get to the point that we could realistically enact such a debt jubilee, then the working class would probably also be strong enough to play Minecraft with landlords.
They would let us do a Maoism on every landlord before they would accept a debt jubilee.
And outlawing landlordry would just mean that former renters have to take out predatory mortgages from banks.
These problems get real easy to solve when you address them both at once though.
If it is coupled with the landlord not owning the property anymore (i.e. the property is turned over to common ownership) then I don’t really see it as a problem.
