Working people with no kids having to pay in taxes at the end of the year

People who don’t have kids and work all year only to turn around and have to PAY MORE TAXES!! Please stop this. I for one cannot have children and personally don’t want any anyway, however I work 40+hours a week in healthcare and my husband does the same for the state and every single year we end up owing thousands in taxes because we “make too much” we barely make it. But if we had kids we would receive money that people like us pay in. It’s almost like we’re penalized for not having kids that honestly we couldn’t afford anyways.
