If the government knew a planet destroying comet was coming, would they say get ready, the world is coming to an end, you're probably going to die? If they knew the economy was going to crash, would they admit it and take responsibility for it? If they knew CME's were going to increase and get bad, would they tell the people?
The government will never admit a huge disaster is on its way, because of mass hysteria and so on.
But some things they could do, is tell people to be ready for disaster. By doing disaster drills. By buying plastic tubs that can hold a few bodies and can be buried. By creating deep underground bases for thousands and thousands of people. By buying milions of MRE's. We know they've done all this.
There could be something heading our way that no one can do anything about. Their only source of money is us. The only way they will remain "the world leader" is by having their money source survive too. It would be wise to try and get people ready for disaster without causing hysteria.
Just an alternative to the conventional theory they're only out for themselves that I believe could be true.
