> markets have all the information

Markets do have all the available information. But no person or group of people can ever process all the information in a meaningful way. Only the market itself can process the huge amount information dispersed among participants.

The rest of your post is silly "animal spirits" pseudo-keynesianism. No, the government cannot usefully manipulate the business cycle or limit damage from failing businesses. Even Keynes himself only ever really tried to say government could stop a major slide from happening in the first place. He said it would be too late to intervene post-crash.

Markets don't have all the information. You didn't disprove that.* My point is that someone needs to help with making "all available info" (whatever that means) possible in the first place. It's not always efficient for markets to do that themselves, at least upfront.

*For markets to have all information upfront, it means we know exactly how the universe works and we can predict that an 8.8 earthquake is going to strike Chile on February... etc. Because of this, markets are greatly reactionary and my point above is also that markets don't always react rationally. I'm not arguing that they are not the most efficient system we have under most industries, also--to be clear.
