As a vegetarian, I can't really comment much on meat quality, but there were a number of scandals in Germany w.r.t. to meat (google "Pferdefleischskandal" if you know German). Again, though, this doesn't reflect on the wealth of Germans as much as on the relative importance of good food (especially compared to e.g. French or Italian people). I don't know if it's a result of my generation's parents or grandparents growing up in the aftermath of WW2, but "cheap food = good food" is an equation that many Germans would agree to (and which I personally find quite strange). I see a lot of people that always buy the cheapest food, but then they have an iPhone, a fancy car, a house, etc.

This is not to say that there isn't poverty in Germany. There definitely are a lot of people who are just getting by, especially after the Hartz reforms, although the social security net in Germany is still quite good. But it's not like nobody is well off.
