By recreating overtime pay, increasing the minimum wage and stopping the buy back of public stocks we would boost our economy and put people back to work. The market would flourish with real goods and service. We would all benefit, even the wealthiest! The companies would have to produce more, pay their employees more which the employees would buy more goods and services. We would also reduce poverty and government spending on public assistance!
