California as of yesterday is ahead of both UK and France. Yeah its impact would be huge.
*sigh* You're thinking about it the wrong way. A bankrupt California wouldn't seize up the US the way countries like Greece or even Cyprus could do to the EU. It's not that California going bankrupt wouldn't have an impact. It's that the impact wouldn't be enough to the US where its mechanisms to deal with it would grind to a halt. When you compare the economy of California alone to a country like Greece, whose economy is only a fraction of it, and then realize that Greece put the EU in a serious crisis for quite awhile in a way that would have been resolved by the US already in the event that a "California crisis" happened... it's honestly pathetic.

It's a comparison of the grave inadequacy of the EU to deal with such issues.
Case in point;
Detroit went bankrupt in 2013. The Detroit-Warren-Livonia area had a GDP of almost 227 billion. The GDP of Greece in 2008, before it plummeted, was over 354 billion. Yes, that's a difference of 127 billion but when we're talking economic powers like the EU and US, that's a drop in the bucket. When Detroit went bankrupt, the US practically went about business as usual and the area actually saw GDP GROWTH in 2014 to almost 237 billion, up 10 billion from the year before when one of the biggest cities in the US, the focal point of that area, went bankrupt. Greece took a fall and the EU shame its pants for years after.
