Standard deduction and 1099-NEC

Trying to help my daughter with her first time filing. She is a full time college student and had a couple of small sources of income in 2022. She made just over $7K in total, from two different sources, both sent 1099-NEC. I am just learning that not only standard deduction does not apply to this situation, but she is also taxed at 15% instead of the lowest 10% tax bracket. Is that so, is there any way around this and, if this the case, is this justified by some kind of rationale? Why is a college student who made a few bucks on the side being punished?
