Certainly there is a lot of variation between recently laid, consistently produced bricks and things done hundreds of years of ago - there is a lot of variation in Germany too.

But with some experience in pushing people in wheelchairs here, I can say that the German sidewalks definitely stand up well to comparison.

It also occurs to that Germans use fairly heavy and largish bricks in general, while the stones I have seen in American are quite small.

There is a German company, Uni (or Uni-eco) that has patented a paver with a small spacer that leaves a gap between laid pavers, to allow more water to infiltrate into the soil. Neat idea, they are sold worldwide now I believe.
The key with pavers and indeed any pavement is the base. I think inproper base preparation is often the reason you see them fail.
They are going down my street now and tearing up and repouring 5-20 foot lengths of concrete sidewalk where the sections have heaved, mostly due to tree roots.

<q>there is a lot of variation in Germany too</q> You can say that again. The roads and bikeways in Kreis Koblenz are mostly awful for a road bike compared to the roads in Niedersachsen (or for that matter southwestern Indiana).
