I had a thought the other day in relation to how impossible it is for a large country to make everyone happy with broad policies. There are big differences in opinions, values, economics, and cultures across a population. What one city, county, province, etc prefers for policy seems to be universally be overridden by "higher level" governance levels going to the top if they so choose. Are there any countries where lower level, more specific jurisdictions get to set policy overrides instead of vice versa? Like, a place where nationwide laws are defaults, but smaller hierarchies can pass laws to supercede the higher defaults?
