Untrue. And patently, factually so.
Were it true, the 2000s would've been a great decade, because Bush cuts taxes not once, but twice. And the 2000s were the worst decade for economic growth since the Great Depression.
Further, taxes have dick-all to do with job creation. ANY good business owner will tell you this.
If a business-owner could reap 100% of the profit for his good or service by doing everything himself, he would do so. Employees are only the result of demand - either the owner's demand for time NOT working or customer demand being too great for the business owner to meet on his own. Thus, the business owner seeks the right wage to get the best employee he can find for the best value. If he underpays, he gets employees who don't help him meet demand. If he overpays, he loses money.
If Bill Gates would've knitted tea cozies instead of creating computers, Microsoft wouldn't have nearly as many employees as it has today. Why? Because there is much greater demand for computers than there is for tea cozies.
ALL economies grow because of consumer demand and ONLY because of consumer demand. China is the finest example. Even with the global collapse, their growing middle class keeps demand SO high that their economy can't help but grow.
It's all about demand. Always has been and always will be - despite what Republicans try to say.
