Not just the news media although I agree they are very negative. Advertisers like to terrify us saying things like there are more germs on our vegetable chopping board than on our toilet seat.
No sooner did scientists get us to lower our laundry temperature to 30 degrees for the sake of the environment than advertisers were telling us our laundry may look clean but it could be full of germs washed at lower temperatures and trying to sell us anti-bacterial for our laundry!
We are made to feel ashamed of our cell phones, TVs, cars, tablets, homes, furniture if they are not the latest and best. The negativity is endless. Don't get me started on Xmas advertising, your whole house is rubbish and everything needs replacing before you can invite friends and relatives in for a meal and socialising.
The media are shameless trying to benefit from other's misery. Interviewing grieving people in war zones and dragging every bit of sadness from them. The world is so much better than it used to be. Often news stories are dropped immediately as soon as things improve. You often find yourself thinking what happened about that news item a week ago but the media have lost interest if a problem has a positive ending.
