Productivity and inequality

At some point the gap between inequality and productivity must make people move between the two spaces to reduce the gap.  How does that not happen?

There are barriers, such as the social capital of being from a different class, though these can be overcome after a certain point and return reach an extreme level; there is ignorance of the ability or requirements that are necessary to move; there are other barriers such as legal and educational constraints.

What determines this gap?  It is clearly larger in the US than in Germany or some Scandinavian countries.  Do these constraints have other effects?
