Terrible example.
First, if someone loses their gig, they most-likely will get a severance and benefits for a while to keep him/her afloat. Second, even if this person loses or does not get a severance, the bank's not going to pound on his door five minutes later to take all his/her things and throw him on the street and into the bankrupcy courts. Third, the person MAY find a new high-paying job pretty quick, especially if s/hes got the skills to have a $135K/year job in the first place. And finally, even if s/he stays out of work or only gets a $50/K year job, the person can sell that fancy house and boat and car and have to live off his/her NEW means.
You make it sound like you lose your job and five minutes later youre in bankrupcy and thats far far far from the truth.
