Again, we are assuming these people are not going to pay on that mortgage verse going out and renting and STILL not paying on that mortgage. In that regards it is a net gain for the consumer economy and was the context of the discussion.
The damage from not paying is done(or at least temporarily papered over). The effects from them not picking up new housing expenses still distorts the economy in a positive way, at least theoretically.
A safe assumption is the economy takes another leg down when they get kicked out. 1) from them having less money to spend 2) from the additional inventory getting released to the market.
