On principle alone I would never invest in Government backed companies, its immoral and dangerous, for they must reap what they sow if we truly want to move on forward with sound policies, otherwise we all will reap stagnation and loss of liberty.
I heard on the news the other day that GM LOST an average of $3,700 per vehicle sold in 2008. That's pretty amazing, since the invoice price represents a 100% markup of a vehicle over the costs to produce it, in general. Then there's GMAC financing.
