Poppy,
On your argument, GM shouldn't get any federal money but rather should just shut up shop & go home.
The issue is not the viability of a particular business, but retention of an industrial base and related skills, as a national resource.
That's why we pay gazillions to build subs & warships here, rather than just buying them all off-the-shelf.
But then again if the government doesn't want for us to have the skills to be able to fix things onshore, then fine, let the business concerned either sink into the swamp or send everything to Manila or Xiamen.
