"The asset rich lose out and the asset poor are able to acquire assets at fire sale prices and, in turn, become asset rich as these appreciate."
But as pointed out, even in a massive 30% fall in assett prices the assets asset not more affordable, because the asset poor need to borrow money in order to buy them. Deposits required are going to be significantly larger, which limits the amount that someone can benefit.
What you are advocating is that the asett price falls, and everything else remains the same, from the size of the deposit, to the amount banks are willing to lend, to the criteria under which they will lend.
That doesn't happen.
The "fire sale prices" don't occur because only those who are forced to move, due to redundancy, death or divorce actually sell their homes. Everyone else stays put, creating a shortage of properties on the market.
What happened the last time, and the time before that, and before that, is that the cash rich are able to snap up the properties that are available and out compete the asset poor.
They are the ones that benefit, not your average Joe.
Like I said, your idea requires everything else other than house prices crashing to stay the same. It doesn't work like that.
