>'The main way to increase home prices is to make the monthly payments lower than before, by either decreasing interest rates or extending the maximum mortgage loan length"

>"Regarding tax, if you let interest be deductible from your taxes, you are making mortgage payments even lower. Again, this raises home value because mortgage payments will again revert to what they were before."

But these two policies/practices also allow more people to become homeowners and part of the "landed gentry." Isn't this acceleration of home values a side effect of encouraging home ownership rather than a strategic attempt by the segment of homeowners to keep other's out? I think you are making this side effect out to be something conspiratorial and I just don't believe there is any such unified home-owner voting block.
