What the bracket actually applies to
US federal income tax is charged in bands. The standard deduction comes off first, and what is left is taxed a slice at a time: the lowest band at its rate, the next band at its rate, and so on. Your bracket is the rate on the final slice — never on all of it.
That is why someone on $100,000 sits in the 22% bracket while paying about 13% of their pay in federal income tax. Nothing has been avoided; the lower bands were charged at their own rates and the deduction was not charged at all.
