I need 3 reasons why Democracy is in decline and 1 possible counterargument.

Failure of governments, too much of a rise of authoritarianism and fascism, as well as immigrant worries.

With the immigrant thing they are worried about not having any jobs left and then that'll make it so they have less say.

authoritarianism = the enforcement or advocacy of strict obedience to authority at the expense of personal freedom.

fascism = an authoritarian and nationalistic right-wing system of government and social organization.
