Because that's how the system was built. Sure, tear said system down. But there will be consequences. You'll see consumption and tax revenues drop through the floor. You've got millions of homeowners 50+ who are expecting to use that asset value to live on, and that will need to come from somewhere else then (most likely social security and medicare topped up from federal tax receipts).

We're just arguing over how we squeeze the ballon; the size of the ballon stays the same (for the most part).

"The Baby Boom generation possesses enormous home equity, which by some estimates exceeds $6 trillion. Despite this mountain of housing wealth, many Boomers will face financial insecurity in retirement. According to one study, between 30 and 40 percent of Boomers will have insufficient income at age 70 to adequately replace their pre-retirement earnings. The extent to which Boomers and preceding generations might be able to draw upon their housing wealth to enhance financial security in retirement hinges on multiple factors, including:

* the amount of home equity that older adults of different socioeconomic subgroups hold today and will likely hold in the future

* seniors’ willingness to tap housing assets in retirement

* the barriers that older adults might face in extracting home equity to finance retirement spending."

"For most households, a majority of their wealth derives from owning a primary residence, and the authors find that the proportion of households aged 65 and over who own their homes has held up quite well despite the housing bust and subsequent homeownership decline. Whereas the overall homeownership rate has fallen to multi-decade lows in the wake of the housing crisis, the proportion of older adults who owned their primary residence was 78.2 percent in 2012, slightly higher than it was in 1998 or at the peak of the housing bubble in 2006."
