On the level of your personal contacts, when you start up, you'll mostly not be (morally for example) supported in your intent by your family, friends, peers. Most Germans want a secure job, working hours from nine-to-five, their (circa) 30 (working) days vacations etc. And will most likely aim for that (or eventually fall into the safety-net of the social state) than risk starting their own business.
Second problem is your future: If you start a company and it fails many doors will be (in many cases firmly) closed afterwards making it harder and harder with every failure for you to start again.
I'd say that a safety-net everywhere (!) isn't good. Because, when you put safety-net everywhere, everything becomes overregulated. Favorite joke in Germany is that, because most garages don’t have windows and laws forbid working environments without windows, Apple, Hewlett-Packard and many other garage start-ups wouldn't be possible.
