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 anyone can predict whether a downturn is temporary or an industrial shift you can make enough money to never work again.
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?
Government support for reduced working hours is also limited to 12 months
