I agree it's not a problem for the US or the markets. That scare has been baked in sooooooo many times that when they finally default, the market will probably go up. Remember when Jobs unfortunately passed away, the stock barely moved because there were so many prior scares that had already factored that in to the price.
So Greece MAY get their ducks in a row to receive the LAST $8B from the IMF, so they can then turn around and pay the IMF back $1.6B by the end of June. Greece currently has a total debt of about $360B and a borrowing rate of 24%. Does anyone honestly believe that Greece is going to do anything other than float along for four more months before the IMF money is used up and they have ZERO funds to service their massive debt? This is such bologna. At some point, they've got to stop loaning money to a country that has less than zero hope of paying back their loans.
Never could quite understand why CNBC seemed to always bring on anti-Apple bashers but now it makes sense. With Apple a huge threat to Comcast's cable TV enterprise, it's absolutely no surprise their wholly owned financial channel would be constantly parading out negative stories and analysts on Apple.
