I sure as hell don't want a system where you vote in the government you expect preferential treatment. I know it can happen to some extent but the less the better. so London did not get the shaft: in fact, they benefit like everyon eelse by having a government that at least in this case did not get involved in trying to determine who the 'winners' will be.
Why is everyone saying the government bailed out GM? It sure as hell didn't bail out their shareholders. So it wasn't a 'corporate' bailout at all: if anything, it was an employee and supplier bailout.
If they hadn't done it there would of been bigger losses on the part of jobs and suppliers, and the effect would certainly have cascaded throughout the supply chain, but somebody would likely have come round to take another stab at the thing with basically the same or better terms than the government achieved.
Bankruptcy is an extremely important strength of our system.
