Depends on your position I guess. If you are a worker at a conveyor belt, it doesn't make sense to work more to produce more cars nobody needs. I think originally this policy was designed to save jobs during temporary downturns, not to save industries going downhill
If you start with a couple hundred thousand $, I can see that. But if you start with like $10,000, how do you stop market fluctuations from eating your money before your correct prediction turns into runaway compounding gains?
