Trickle down didn't work when Reagan did it and it's not working now. And giving money to people to spend doesn't really work that well either. Companies see an increase in sales but it's temporary so there is no point for them to invest in more employees. Especially when your current workforce can handle the demand.
I do agree with you on your idea of offering tax cuts IF they hire a certain number of new employees and maintain that number throughout the year in order to qualify for said tax cut. It's actually not a bad idea. More workers means more production and less hours needing to be worked by current employees. It also means less people on welfare programs and unemployment and also means more people with disposable income to stimulate the economy.
Try not to judge someone based of off an obviously sarcastic comment. Seems to be a big issue with people on MMOC not being able to pick up on sarcasm. Or maybe I'm being far too subtle. Who knows.
