My very first sentence explains why I think his argument is weak.
I agree, I have stated no position on the absurdly rich and increasing inequality. I think it is unnecessary to stray into this area in order to prove or disprove whether businesses or the wealthy create jobs. Either a business or a wealthy person can or cannot create a job regardless of the taxation laws du jour. He has categorically stated that they cannot. I think this is totally incorrect.
No, he stated that they do not. Businesses don't hire employees they don't need. They can, but if they try it at any appreciable scale relative to their business, they will go out of business.
It's not about what can happen. It's about what does happen. And what does happen, is that employers hire employees when they need them. Not just because they've made money, nor just because they got to keep more of the money they make via changes in taxation.
They could. But they don't. There's decades of data and research on this. It's not really debatable. Tax cuts do not translate into jobs. It's never happened. The increase in wealth of the wealthy does not translate into jobs. It's never happened. Consumer demand and business expansion to meet that demand, does translate into jobs. It always happens.
The question is how, or even whether you should try, to stimulate consumer demand when unemployment is high. (And the follow-on: what problems does that (in)action create)
