Should I live here?
If I had a government like representative democracy I wouldn't really mind because they're just voting for people to represent the government. That isn't that hard and also we kinda already have that type of government. So, I would say yes I wouldn't mind living here. Here are some countries that have this type of government: Canada, United Kingdom, United states of America.
