As someone who thinks the future is going to be fucked no matter what we do at this point, I'm in favor of propping up the house of cards for a little longer.
imagine that the effected areas of the u.s. economy are a huge sun. imagine that sun has reached it's full size. and now it begins to burn up it's resources.
imagine that once huge sun finally burning up so much of it's core resources that it eventually collapses.
what you have left is a black hole.
a black hole exerts such an over arching amount of gravitational pull that it sucks in all manner of matter and anti-matter. not even light can escape.
letting it crash is a very bad idea.
