The mainstream economists do not believe:
1. That tax cuts to the rich is an effective stimulant.
2. That eliminating social security and other welfare is beneficial to the economy.
3. That Ayn Rand was describing a viable society economically.

The reason they don't is your beliefs fail the scientific method. Supply side economics was tried and failed. Just because know nothings like Rush and Hannity don't believe it doesn't matter in the least to them. The scientific method is about trying it and evaluating it. It turned out to be a load of nonsense that just added enormous debt. Likewise the mainstream economic community believes a combination of the welfare state and a capitalistic economy is the soundest path to prosperity. As to Ayn Rand it was just a novel, get over it.
Economics is a serious science with a lot of mathematics, and people win prizes for brilliant work. Your ideas don't work. Normally I wouldn't care what nonsense you believe in but the application of rubbish like this hurts people's lives every time it is tried and falls flat on its face.
It's like if you don't agree with engineering formulae, every rocket you build is going to crash. There's nothing mysterious about economics, it's a science not a repository for hopes, dreams, and wishful thinking.
And until mainstream economics takes your ideas seriously I certainly won't be. I can only feel sorry for the people who lose their jobs and assets because people like you can't face reality.
