Eminent domain can be "legal" or "governmental." Eminent domain could also be viewed as "unjust" or "cruel" depending on its implementation.
A <u>democratic government </u>gives citizens the right to directly vote gov't officials into office to represent them.
On the other hand, <u>authoritarian regimes </u>are built from strong central governments with little to no political freedoms for citizens.
So, the primary different between a democratic and authoritarian government is the <em>citizens' political power/freedom</em>.
