Earlier quoted context omitted.
Because if the Big Three go under, a very large number of workers (folks working for the Big Three and for their suppliers) will suddenly be collecting unemployment insurance instead of paying taxes and they will also paid in taxes if bailed. so GM is going to become a giant money laundering operation for the IRS? cut out the middleman and put them on unemployment...then they can actually find PRODUCTIVE work
The unemployment would cost the government more than the bailout. One could argue that it would still be better off in the long term for the government to bite the bullet and pay that unemployment money than to keep the US auto industry afloat; I am partial to that argument myself. But I'm responding to the "why should a waitress at Denny's..." question.
The wage of an auto worker costs from $1200/week to $2920/week (depending on whether you believe the $30/hour number or the $73/hour number floating around).

Additionally, auto workers have an incentive to get off unemployment; it pays less than market rate. They have no incentive to stop working for GM, which pays above market rate.
