CO State taxes are (roughly) 5% which puts it right in the middle of US states (between 0% in places like Florida and 10-ish percent at the (non CA/NY) high end).
Then factor in (roughly) 35% federal + local taxes ... let's call it 40%, give or take. Let's just forget property taxes for the sake of this discussion.
Why should I think of 40% as a "low" taxation rate ?
Why shouldn't I expect a high level of government services in return for 40% taxation ?
(FWIW, I live in CA so you can add 5-8 more percentage points for my own tax burden ... same questions apply ...)
Even at $100k, you're around 31% total. That's for CA.

I don't think the suggestion was that lower income brackets should bear that burden.
Therefore it only makes sense to discuss the highest brackets.
Although better than most other U.S. states, I don't have access to the services that Norwegians do. But my taxes are also very low here. We could have the same kind of services as Norway if we want to pay for it, but taxes would have to go up.
Until Americans stop thinking of the word "tax" as evil, we'll always value it wrong.
