Pretty sure there’s more to this then what you’re reading.
Yes, of course a man is responsible for his children, he should contribute support to them. Notice the word contribute. In a divorce when the woman gets the kids she also has a responsibility to share in the support of those children. However the idea that most judges have that somehow the family can live separately and yet the man can still support everybody to the same degree is incredibly bad and bigoted mathematics.
My sister-in-law collected child support for 10 years never spent dime 1 on the kid. My wife and I and my mother-in-law bought the child all of her clothes and incidentals.
The point I am making is that when you read a short piece like this it’s about a 95% chance you’re getting a very incomplete picture. It’s best to keep that in mind
I have zero idea the background other than the girl said in the video her dad had not tried to see her in years. She just turned 18 and wanted to turn an embarrassing situation into something positive.
I try not to generalize people or situations and take each person and event that I learn about as it’s own.
And then there are people like me. Who raised my incredible son without the deadbeat father and never asked for a dime. Nor ever received one. As you said. There are all types of back stories. Generalizing based on your experience should not be a blanket opinion. I try not to judge deadbeats the same. I’m sure they have their reasons.
So, your sister in law didn’t have to buy food, rent, and utilities? Child support is to help with the cost of raising a child, including all of the above.
