Harris' plan still gives no tax relief to the vast majority of workers, but there are so many really low-paid service workers that are expected to make up their very low, if not legally below minimum, wages in tips that I can't really get too worked up about unfairness like that.
Edit: copy/pasta of the relevant bit: "Vice President Harris is proposing a new plan to get tax relief to more than 100 million Americans. Her plan will expand the Child Tax Credit to provide a $6,000 tax cut to families with newborn children. Unlike Trump and Vance, Vice President Harris is committed to ensuring no one earning less than $400,000 a year will pay more in new taxes."
