When you talk about how the economy is doing bad and how stocks are falling or will fall and how you should totally get safer with your investments, then people do listen to you, maybe not all but most will listen to people on TV if they repeat it long enough, hell even the highest educated intellectuals would have to eventually convinced because if you hear about it for weeks after weeks in every channel you will start to think it is normal.
However, when media does that people do sell and that selling does make it go down, it didn't go down because of any financial reason, it went down because people sold and became desperate, which made media 50% right about it.
Moreover, those companies make it for cents on the dollar in some Chinese company and if they can't than they pick another cheap country to build their factory in. This can't continue forever because the more jobs that goes overseas means the less jobs available in USA and there would be less buyers and that would make companies go bankrupt eventually. Just look at how many people were fired this year in USA and you will see why the country is going bad.
