Should the U.S. still be considered a democracy at this point?

Im not American but I want to address the wider point about the western world. The impact of Trump on this and American distinct things are for others to comment on.

There are degrees of democracy. Some countries have formal democratic structures but no free press or judiciary (Russia, Hungary and lots of African nations). Most of the west has these things but with the scales tilted heavily in the intersts of the rich and powerful.

This type of democracy we have now isnt perfect but its the best we have had. Its important to say that it wasn't founded as a result of liberal philosophy or the French and American revolutions. It came about because of the increased power of labour union movements from the late nineteenth century onwatds. Economic power eventually translated to political power as the ruling class had to compomise in order to prevent socialist revolutions and keep their workers producing for them. Women also had to fight hard to get the vote.

Now unions in many countries are weak, capital has power like never before and nation states have much more surveillance capabilties because of technology. Automation may well further undermine the economic and political power of workers.

So yes, Democracy is slowly being eroded and it has been for years. Its not just about Trump or the nationalist right, though they are a symptom and perhaps an accelerant too.
