Social media and other addictive Internet sites - people are constantly glued to them, even on their work, which decreases their productivity. Social media also cause depression in many people, because they not only procrastinate, but also constantly compare their life to others, which leads to dissatisfaction. Also social media are good at spreading lies and fakes, which can have negative effects on the economy - anti-vax panic, anti-GMO, political manipulation and so on.
guilty as always. i have been using my facebook account in my phone just to check how bad the politics in our country. the fake news being told over and over, the constant battle of these fake news are consuming the hours i got in a day. i have been reading them all though i don't reply to them, it tell us how divided the country men when it comes to supporting the government. i guess the chinese are doing better after banning facebook.
