And then there's the other issue that a failed founder in Germany is pariah. From reading here and elsewhere, in the US you seem to get a reasonable chance (and maybe even some recognition) for having tried to start a company (and managed to keep it alive for some time). Here, you failed, so you will fail, so why should anyone employ you?
In a (possibly flawed) attempt to cheer you up: be aware that you basically say - failing is frowned upon in Germany - I do not want to run that risk - so I will not try to start a company Thereby effectively continuing the mantra "do nothing you could fail in". I think that entrepreneurship has got a lot to do with "acting in spite of" and would not assume the situation in the US (I don't know personally) to be like…
There's probably a kernel of truth to the idea that Americans are more entrepreneurial and less judgmental than your average European, but the idea that, in Europe, failure turns you into a pariah seems like a nasty myth that becomes real simply through repeated mentions.
