I disagree there the "smashing of house prices" will be a disaster
If someone bought a house 10 years ago for $200K that is now worth $1 mil and in the future it went back to being worth $200K, then there is no real problem
A completely different situation of someone bought a house for $1mil and it dropped in value to $200K especially if the house is mortgaged.
a drop in property values of this magnitude would be a disaster for the whole economy and would assist no one
