As I see it theres several parts thats required in a Representative democracy.
A free and independent media.
A democratic economy.
A Real choice between candidates.
A voting system that is not subject to manipulation.
There are surely more things and I don't think Representative democracy is the end all form of society, there are levels of democracy and we can have more.
However I don't even think theres one state today where representative democracy actually works.
A good measure of this is to check the polices the elected take and public opinion on matters. As far as Sweden goes there are today several anti piracy laws that 80% of the population are against. Other things considering swedish tax money leaving the country thru venture capitalists is also something 60% of swedes disagree with.
As for as the US goes when asked about welfare most people are against it, but if you state the question "should the poor recive more money" 80% agree. There are probably lots more examples because i see them every day.
A big problem aswell is that media in most countries is dictated by the same people that ownes the world or atleast 80% of it, so its not hard to figure what views comes out of this.
Do you think we have functioning democracys in the world?
if not what is the problem?
