I still don't see what makes Schumacher unique tho, particulary if both his parents had an income... that makes a huge difference... other drivers (some of them I mentioned) have a similar background.... can you explain, what makes him unique?
I think when you compare Schumacher's situation to Vettel's (and that's what you usually go on about) you also have to consider the fact that by the time Vettel came along, exactly Schumacher's success and example made sponsors more interested in supporting kids and karting. Schumacher's success did have a big effect on motor racing in Germany in general. Before Schumacher Germany never had a F1 WDC and the last race winner they had was Jochen Mass and before him Wolfgang von Trips back in the 50s. So even if Schumacher and Vettel came from similar backgrounds I still consider Schumacher's story more unique because he was the one who set the example. At least in Germany.
