Absolutely not. I'm saying that high tax rates and high levels of direct government benefits from those taxes stifles innovation by reducing the incentives to be innovative.
Does it make for an "equal society." Sure. But that also means that you don't reward people with innovative ideas or who go way above and beyond. Sure they could work their ass off to make their idea a reality....or they could just not. It's not like they'll get massively rewarded for it. Plus the government probably gives them what they need already.
Yes there is a sweet spot and infrastructure is important. If the government doesn't do anything people die on the streets which is A. Inhuman B. Makes people more concerned about not dying over anything else. I also think promoting good education is really important so you give people a path from nothing to something. Who cares if you make it rewarding to succeed if it's absolutely impossible from birth for some people.
I can only say the US is the closest sweet spot just by the results. It's absolutely not perfect, but the US is specifically known for its Innovation and productivity.
