American Economy - Computer Simulation

Does anyone remember a post that was on here about a year ago regarding a thinktank’s computer simulation of the American economy?

The think-tank found a way to get something like guaranteed 2-3% economic growth for the next 150 years.

I believe they eliminated all taxes except income taxes, had a flat taxation rate, and completely deregulated all goods and services.

If this rings any bells and anyone knows links to any sites/articles describing this simulation PM me or post them here.
