Innovation often leads to a reduction in staffing and as such, a reduction in payroll. Less payroll equals more profut and an increase in the likelihood of expansion.
Increased salaries is the result of an increase in business not the cause of it. Liberal nutters who believe the nonsense that increased wages are the cause are putting the cart before the horse.
If I make a widget component for a gadget, and I increase the salaries of the widget makers, sure, they have more money but they aren't buying widgets are they? No, they are buying food, clothing, alcohol, paying rent, utilities, etc. B, you could say that it all melds into one giant pot and eventually, more widgets are bought but this is a very slow process and not even a sure thing. Meanwhile my business goes into the red waiting for it to happen.
No folks, as the smartest of us know, a good economy increases wages and it does so all across the job spectrum. It's complete left wing nut nonsense to say otherwise.
