Every single policy is crafted so as to not harm the actual value of existing homes.
I will repeat something I've already said hundreds of times, you cannot have both affordable homes, and home prices that keep going up.
Even if we managed to stop the prices so they never rise again, it would take the better part of a century to make them affordable through just wage growth.
The only realistic path to affordable housing, is by causing ALL home prices to fall. Which is the exact reason we never implement policies that will actually solve the problem, there are too many home owners who will not vote for a party that slashes their house value by 50% (and we actually need around a 80-90% drop to make them affordable in some markets)
