Democracy as we know it is only about 100 years old. It's not like some ancient venerable institution is crashing down. Governments are shaped by their people, not the other way around. Flux is their natural condition.
Modern democracy is only a hundred years old, ancient greece is the bedrock to democracy. And rome actually had democracy somewhat into practice within the senate. In fact the us system is a mirror to romes in many ways. Especially in the fact that we are a republic, much like Rome was. More accurately the us is: A constitutional republic. Any way point here being, Democracy is actually a little older then you give it credit for. But that's just heresay theresay.
My take on this question: The only threat to democracy is the way, the far far left and the far far right takes stances on handling today's issues. Creating moral issues where there is none and taking moral authority in any debate with the intention to silence the other side whilst holding onto the microphone. The only difference between the two being that the Right calls for smaller government. The left these days seem to call for bigger government. Meaning higher taxes, more over reach, etc. Which does indeed put a threat on the democratic spectrum. Asking for the government to play a part in matters that should not ever concern the government, only takes power further away from the people. A few off the cuff reasons big government will never work the way idealists wish it would:
1) The government is doing things it shouldn't be doing: How do you think Burger King would do at selling perfume? How would you feel about eating Purina brand hamburger? How about discount shoes sold by Rolex? If the government were simply building roads, throwing up a few street signs, securing the borders and making sure rotten horse meat isn't being sold as steak in the local supermarket, it would probably be relatively good at its jobs. But, when we have the government declaring your yard a wetland because it rains, micro managing what kind of light bulbs you're allowed to buy, bailing out big corporations and forcibly taking over our health care, of course the government does it badly. Just as you couldn't be a talented brain surgeon, race car driver AND Navy SEAL all at the same time, the federal government simply cannot be all things to all people.
2) The late, great Milton Friedman once said,
“When everybody owns something, nobody owns it, and nobody has a direct interest in maintaining or improving its condition. That is why buildings in the Soviet Union — like public housing in the United States — look decrepit within a year or two of their construction…” Our government already has a lack of responsibility for it's actions. All governments do. Bigger the government, the bigger their shrug when they want a lack of accountability. As an example, Obama takes no personal responsibility for the Affordable care act not being so affordable, Hilary Clinton takes no real responsibility for the dangers her Email scandal put on foreign agents or her role in Benghazi, and Our president elect Donald J, Trump is doing the good old government shrug. "I dunno about no Russian hacking" lol. Point is, when your accountable for something the best thing you can do is ignore it and never say sorry. Just like when you get in a car accident, never say sorry or else you take responsibility for what had taken place. Our politicians are very practiced at it.
As you can already tell, I personally agree with this poster actually: ReijiTabibito :
The issue with democracy - particularly in America as it stands right now - is whether it can get over its current trend of swinging too far to the authoritarian side of things. (And this is my argument against both the GOP and the Democrats right now.)...
People have public outrage over many small issues these days and look to the government over what can be easily argued as; Personal grievances of an ideological standard. Bringing the government deeper into our lives like this in order to police inner circle issues between race, gender, etc makes a bigger government and is not in your best interest for democracy. All in all this is what a career politician wants. They want you to try and bring these kinds of walls down so they can build them back up with less and less of 'your rights' to stop them. Like gun control: Of coarse the left wants to take your guns away, it is your number one defense against your goverment. I dont know how or why most people dont know, but I blow away a lot of peoples minds by informing them that the second amendment was not put into place so a bunch of rednecks can go hunting but rather, it was put in place by our founding fathers. Fresh off of fighting a war for their own liberty, from the tyranny of their own goverment. So that in the inevitability that the Constitution fails to protect it's people, the US people can rise up against their own goverment. Anarchists literally putting in a kill switch for future anarchists. They knew that any government, including the one they were forming, could inevitably fail it's people. And that is some special lack of hubris right their on part of the founding fathers. Bravo *slow clap.* Also, just to put that point on gun control home: I dont own a gun, only ever fired a pistol once and cant tell the difference between a semi auto or fully auto assualt rifle and even I knew the important fundamentals of why our second ammendment is crucial to our constitution. I mean, unless you want to have our future uprising be a bunch of pistol's versus swat with tanks. (Yep, there is inner city police departments fitted with military grade APC's these days. : http://www.popularmechanics.com/military/weapons/a18590/when-police-get-armored-personnel-carriers/
None the less it is this authoritarian mindset people have begun to grasp onto that is literally choking democracy in Europe and here in the US. In fact, and I know this is controversial to say. But the most democratic action any of these governments made in a long time was the UK leaving the EU. Wether it was better for the country is up to debate, but no one can argue the solid fact that the people voted and their government obliged. Leaving what I dare say, is the least democratic thing in this modern day democratic circle jerk. (Cough cough, the EU cough.)
~ The EU: Making democracy more socialist, one step at a time.
Joking about the EU and it's slow, slow, slow inevitable failure aside: In the end if your a tinfoil hat wearing mother fucker like me, your real concern for the future of democracy mirrors the original Deus Ex game, government bail outs for corporations and dependency on corporate funding wrapping them up in corporate schemes. This is the truest threat to every ones freedom: The inevitability that the government will be so entrenched within corporations that it is truly the corporations running us all.
