Social media and other addictive Internet sites
Good answer! I also despise social media like Instagram that encourage bragging about social status, e.g., photos of food at restaurants, luxury cars, vacations, etc. It severely affects inexperienced people, who think that it is the truth (and that's how we should live our life). What most people don't understand is that the "true" rich people seldom brag about their wealth in social media.
Social media waste our time and encourage unnecessary consumption.
