I thought he mentioned working lots of overtime in the video
To save up the cash for a car? Or because he has outrageous debts from financing stuff like this? It's not clear.
60 hours a week in a factory to afford it, is what he said. I think it's just straight-up legit. Also, this, from his Reddit, kinda says it all:
"My dad has been everything to me, he is not my biological father but he IS my father. But this man in this video, my DAD my FATHER, was the best thing that ever happened to me and my mom and I hope I can be a fraction of the man that he is. My real father abandoned me and my mother when I was a child, so I understand to a degree how some of you in the comments feel and I am sorry if this video was hurtful in any way."
