There are a number of questions:

• wealth vs inequality (or growth of average vs growth of median - for a number of statistics);

• tax levels - this is one of the usual things associated with the (sclerotic) "European model", but can be quite separate from the issue of labor flexibility;

• unemployment vs total workforce employment (i.e. the proportion of people in a given age category that work);

• total hours worked vs total number of workers (part time schemes, number of jobs per person, etc)

• procedures to fire people.
