Minimum wage in SC equates to about $15,000 per year. She likely is a waitress and declares tips to boost her income. With three deductions and an earned income tax credit, she may have just used money from 'we the people' to cover her rent.
None the less it was a smart move and legal.
I’m not happy about paying taxes so that it can be redistributed as “tax credits” but with that as a given, I’d much rather see it go to the working poor than to the deadbeats.
