Companies are disposable in the US: fear in Europe

Reading Paul Grahams essay "Why not start a startup", I came into a paragraph where he analyses why the fear of incertainty should not drive you not to start a startup:

No one will blame you if the startup tanks, so long as you made a serious effort.
[...]
Nor will investors hold it against you, as long as you didn't fail out of laziness or incurable stupidity. I'm told there's a lot of stigma attached to failing in other places—in Europe, for example. Not here. In America, companies, like practically everything else, are disposable.

Americans are not fearful of failure. Is this fact different in Europe?
Has this anything to do with the post World War II Europe? With the generally conservative and social aware mindset?
